/* uClibc doesn't support many of the C90-reserved C99-defined math
|

functions. Make sure we don't implicitly generate them unless C99
|
| 76 |
|
|
support is explicitly requested. This will affect both frv-linux
|
| 77 |
|
|
and frv-uclinux. Even though the glibc, the primary library for
|
| 78 |
|
|
frv-linux, would enable better code to be generated with
|
| 79 |
|
|
TARGET_C99_FUNCTIONS defined to 1, uClinux can be used as the
|
| 80 |
|
|
library for frv-linux as well, and we'd better have that work
|
| 81 |
|
|
correctly. Maybe we move this to a uclibc.h header in the future,
|
| 82 |
|
|
and use that for frv-uclinux and frv-linux-uclibc? Define it here
|
| 83 |
|
|
for now, such that we can still get exactly the same code out of
|
| 84 |
|
|
both frv-linux-gcc and frv-uclinux-gcc, when feeding them the same
|
| 85 |
|
|
preprocessed sources. */
