The test is compatible with clang as well as gcc, but ISTM that testing for the __clang__ macro is just as potentially error-prone as macros that used to be GCC-specific are now defined in compilers that aim for GCC compatibility. Use a __has_include feature test instead.
Regstrapped on x86_64-linux-gnu. Tested on arm-vxworks7 (gcc-12) and arm-eabi (trunk).
