I would also be interested in an answer to see if this can become a
part of gcc (as well as the has_warning), but you could just check the
defines a header usually makes:

std_header.h:
#ifndef STD_HEADER_H
#define STD_HEADER_H
...
<stuff>
...
#endif /* STD_HEADER_H

my_c_file.c:
...
#ifdef STD_HEADER_H
<do some stuff that can only be done if that header exists>
#else
<workaround>
#endif
...
