Yes, it is.

The flag is -xc99=o
where o is separated list of:
[no]_lib [Do not] Enable the 1999 C standard
library semantics of routines that
appeared in both the 1990 and 1999 C
standard.
all Turn on recognition of supported C99
language features and enable the 1999 C
standard library semantics of routines
that appear in both the 1990 and 1999 C
standard.
none Turn off recognition of C99 language
features, and do not enable the 1999 C
standard library semantics of routines
that appeared in both the 1990 and 1999
C standard.
If you do not specify -xc99, the compiler defaults to
-xc99=all,no_lib.
If you specify -xc99 without any values, the option is
set to -xc99=all.
