Hi,

I've long had this wish: an option similar to -std, but which would not
specify the standard.  Rather, mark a requirement that the standard be at
least a version.

This would be especially useful for libraries, which might for example require
C99 or C11 to work.  They would be able to specify -minstd=c11 in their pc(5)
file (for use with pkgconf(1)).

There's already a standard, portable way to check:

#if __STDC_VERSION__ < 201710
#error C17 required
#endif

Hmm, not my favourite to stick that in every public header file, but yes, it's portable.

But yes, I could provide a <project/__compiler.h> "hidden" header that does all this stuff, then include it everywhere. :)

Thanks,

Alex

Alexander
