Port to PGI 16.10 x86-64
This patch fixes one real bug in gl_anylinked_list2.h, along with
some minor glitches that are not bugs. It does not silence PGI’s
thousands of bogus warnings when compiling test-intprops.c.
Fortunately, the warnings do not cause a failure.
* lib/c-ctype.h (_C_CTYPE_LOWER_A_THRU_F_N, _C_CTYPE_LOWER_N):
Rename parameter to avoid PGI warning about ‘#define f(n) 'n'’.
My goodness, PGI goes back a long ways - this predates C89!
* lib/gl_anylinked_list2.h (ASYNCSAFE): Fix bug caught by PGI.
For example, ASYNCSAFE (const void *) should expand to
‘const void *volatile’, not to ‘volatile const void *’.
* lib/spawn.in.h (POSIX_SPAWN_USEVFORK): Don't define if already defined.
* lib/verify.h (verify) [!__GNUC__]:
Use shorter albeit meaningless string to bypass silly compiler limits.
* tests/infinity.h (Infinityf, Infinityd, Infinityl) [__PGI]:
* tests/nan.h (NaNf, NaNd, NaNl):
Use static functions to avoid misguided compiler diagnostics.
Is there some reason we don’t use static functions on all platforms?
