From 7603f9d38af9d950686319d0ded621e82f4f1694 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 17 Nov 2012 12:24:04 +0000 Subject: gsl: fix build on !i386 uClibc uClibc pretends to implement as it installs the header, but in practice, it only implements the functions for i386. This makes gsl unhappy as it detects fenv.h, but then cannot use the fenv functions.
