From: Baruch Siach Date: Wed, 23 Apr 2014 12:00:03 +0000 (+0300) Subject: libgc: fix build under uClibc X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6bef4893172dda2c186268e630c5e61cb9609693;p=buildroot.git libgc: fix build under uClibc fenv.h is used in a workaround for a glibc specific bug. However, uClibc lies by defining __GLIBC__, but does not provide fenv.h in our default uClibc configurations.
