+/* 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. */
