[cfe-dev] Pragma message in Clang?

[Matt Joiner]

It does, enabling it however seems to drop recognition (I assume C99
is out the window) of _Bool:

./cpfs.h(27) :  error: unknown type name '_Bool'

subprocess.CalledProcessError: Command '['clang', '-c', 'bitmap.c',
'-o', '/tmp/bitmap.c.o.mbECeS', '-fms-extensions', '-Winline',
'-Wshadow', '-Wextra', '-Wmissing-format-attribute', '-Wall',
'-Wfloat-equal', '-fdiagnostics-show-option',
'-Werror-implicit-function-declaration', '-Werror=return-type',
'-fno-exceptions', '-std=gnu99', '-D_GNU_SOURCE',
'-D_FILE_OFFSET_BITS=64', '-DCPFS_SIMD_ALIGNED', '-DCPFS_USE_SSSE3',
'-DFUSE_USE_VERSION=28', '-O3', '-g', '-DNDEBUG',
'-DCPFS_LOG_LEVEL=WARNING']' returned non-zero exit status 1

I don't imagine this is intentional, or -fms-extensions is sneakily
switching language to C++, or clobbering the C standard in use.
