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.
