OK.
Could we just use
-std=gnu99 (with -fgnu89-inline if required) with GCC on Solaris? ISTM
it would be cleaner to just properly enable c99 mode rather than define
an undocumented macro to use a couple of c99 declarations.
Agreed, but what about non-GCC compilers?
Solaris Studio defaults to "-xc99=all,no_lib" which, according to the
man page, enables c99 language features but doesn't use c99 standard
library semantics. isinf is defined to be a macro by c99 and doesn't
require changing the c99 mode so I'd just keep using the defaults with
Solaris Studio for now.
For GCC

gets rid of the warnings and passes tests.
