[patch] assert.h causing problems with older GCC and XLC

[Ken Werner]

Hi,

the assert function is using __func__ whenever __GNUC__ is defined, regardless 
of the language level provided by the compiler. This causes Problem with the 
XLC and probably older GCC versions. This patch first checks the __GNUC__ 
level then the __STDC_VERSION__. Ok to Apply?
