15  This header identifies if the given facilities are available in the
16  standard build environment the current compiler/linker/standard library/
17  operating system combination. This file may in some cases #include standard
18  headers in order to make availability determinations, such as to check
19  compiler or SDK version numbers. However, it cannot be perfect.
20  This header does not identify compiler features, as those are defined in
21  eacompiler.h and eacompilertraits.h. Rather this header is about library support.
22  This header does not identify platform or library conventions either, such
23  as whether the file paths use \ or / for directory separators.
24 
25  We provide three types of HAVE features here:
26 
27  - EA_HAVE_XXX_FEATURE - Have compiler feature.
28  Identifies if the compiler has or lacks some feature in the
29  current build. Sometimes you need to check to see if the
30  compiler is running in some mode in able to write portable code
31  against it. For example, some compilers (e.g. VC++) have a
32  mode in which all language extensions are disabled. If you want
33  to write code that works with that but still uses the extensions
34  when available then you can check #if defined(EA_HAVE_EXTENSIONS_FEATURE).
35  Features can be forcibly cancelled via EA_NO_HAVE_XXX_FEATURE.
36  EA_NO_HAVE is useful for a build system or user to override the
37  defaults because it happens to know better.
38 
39  - EA_HAVE_XXX_H - Have header file information.
40  Identifies if a given header file is available to the current
41  compile configuration. For example, some compilers provide a
42  malloc.h header, while others don't. For the former we define
43  EA_HAVE_MALLOC_H, while for the latter it remains undefined.
44  If a header is missing then it may still be that the functions
45  the header usually declares are declared in some other header.
46  EA_HAVE_XXX does not include the possibility that our own code
47  provides versions of these headers, and in fact a purpose of
48  EA_HAVE_XXX is to decide if we should be using our own because
49  the system doesn't provide one.
50  Header availability can be forcibly cancelled via EA_NO_HAVE_XXX_H.
51  EA_NO_HAVE is useful for a build system or user to override the
52  defaults because it happens to know better.
53 
54  - EA_HAVE_XXX_DECL - Have function declaration information.
55  Identifies if a given function declaration is provided by
56  the current compile configuration. For example, some compiler
57  standard libraries declare a wcslen function, while others
58  don't. For the former we define EA_HAVE_WCSLEN_DECL, while for
59  the latter it remains undefined. If a declaration of a function
60  is missing then we assume the implementation is missing as well.
61  EA_HAVE_XXX_DECL does not include the possibility that our
62  own code provides versions of these declarations, and in fact a
63  purpose of EA_HAVE_XXX_DECL is to decide if we should be using
64  our own because the system doesn't provide one.
65  Declaration availability can be forcibly cancelled via EA_NO_HAVE_XXX_DECL.
66  EA_NO_HAVE is useful for a build system or user to override the
67  defaults because it happens to know better.
68 
69  - EA_HAVE_XXX_IMPL - Have function implementation information.
70  Identifies if a given function implementation is provided by
71  the current compile and link configuration. For example, it's
72  commonly the case that console platforms declare a getenv function
73  but don't provide a linkable implementation.
74  In this case the user needs to provide such a function manually
75  as part of the link. If the implementation is available then
76  we define EA_HAVE_GETENV_IMPL, otherwise it remains undefined.
77  Beware that sometimes a function may not seem to be present in
78  the Standard Library but in reality you need to link some auxiliary
79  provided library for it. An example of this is the Unix real-time
80  functions such as clock_gettime.
81  EA_HAVE_XXX_IMPL does not include the possibility that our
82  own code provides versions of these implementations, and in fact a
83  purpose of EA_HAVE_XXX_IMPL is to decide if we should be using
84  our own because the system doesn't provide one.
85  Implementation availability can be forcibly cancelled via EA_NO_HAVE_XXX_IMPL.
86  EA_NO_HAVE is useful for a build system or user to override the
87  defaults because it happens to know better.
88 
89  It's not practical to define EA_HAVE macros for every possible header,
90  declaration, and implementation, and so the user must simply know that
91  some headers, declarations, and implementations tend to require EA_HAVE
92  checking. Nearly every C Standard Library we've seen has a <string.h>
93  header, a strlen declaration, and a linkable strlen implementation,
94  so there's no need to provide EA_HAVE support for this. On the other hand
95  it's commonly the case that the C Standard Library doesn't have a malloc.h
96  header or an inet_ntop declaration.

859  This allows the user to define a header file to be #included after the
860  eahave.h's contents are compiled. A primary use of this is to override
861  the contents of this header file. You can define the overhead header
862  file name in-code or define it globally as part of your build file.
863 
864  Example usage:
865  #define EABASE_USER_HAVE_HEADER "MyHaveOverrides.h"
