| /* uClibc doesn't support many of the C90-reserved C99-defined math |
| functions. Make sure we don't implicitly generate them unless C99 |
| support is explicitly requested. This will affect both frv-linux |
| and frv-uclinux. Even though the glibc, the primary library for |
| frv-linux, would enable better code to be generated with |
| TARGET_C99_FUNCTIONS defined to 1, uClinux can be used as the |
| library for frv-linux as well, and we'd better have that work |
| correctly. Maybe we move this to a uclibc.h header in the future, |
| and use that for frv-uclinux and frv-linux-uclibc? Define it here |
| for now, such that we can still get exactly the same code out of |
| both frv-linux-gcc and frv-uclinux-gcc, when feeding them the same |
| preprocessed sources. */ |
