Description Andreas Jaeger 2012-05-07 20:02:44 UTC 
As discussed on libc-alpha, the commit below breaks the math library on SPARC.

commit bd7b0e561f7f684cedfc4adb964569fe9ab16209
Author: Andreas Jaeger <aj@suse.de>
Date:   Sun May 6 09:14:15 2012 +0200

    Build glibc with -frounding-math
    
        * Makeconfig (+math-flags): New, set to -frounding-math.
        (+cflags): Add +math-flags so that all of glibc gets compiled with
        it.

The commit has been reverted to figure out the reason for this on sparc. The goal is to apply the patch again, so we need to see SPARC's libm fixed first.
