The following macro is defined in the <sys/cdefs.h> header file. It may be best to include it via the <sys/types.h> header file, which is required by POSIX.
| Type | Macro |
|---|---|
| Idenfication | __BIONIC__ |
The following macros have to be included from the <features.h> header file.
| Type | Macro | Description |
|---|---|---|
| Version | __GNU_LIBRARY____GNU_LIBRARY_MINOR__ |
Until version 5 |
| Version | __GLIBC____GLIBC_MINOR__ |
From version 6 |
Notice that the <features.h> header file does not exist on all platforms, so it cannot be included without further ado. However, since it is included by other GNU glibc header files, a better way to obtain the above-mentioned macros is to include the <limits.h> header file (see e.g. paragraph 4/6 in ISO/IEC 9899:1999).

Notice that I am not sure about the format of __CRTL_VER, but it seems to follow that of __VMS_VER.
