This is should be the case for all library functions. Gcc will only set the variable to a different value if said so and in these situations it can use inline functions etc. Also, the __FAST_MATH__ stuff should probably also have influence. > Uli, please add this to your glibc 2.2 ToDo list. OK, done. But it's nothing I would delay a release for. -- ---------------. drepper at gnu.org ,-. 1325 Chesapeake Terrace Ulrich Drepper \ ,-------------------' \ Sunnyvale, CA 94089 USA Red Hat `--' drepper at redhat.com `------------------------
