uclibc does not have nether sin(float) nor cos(float) used by glxgears in all ebuild versions of xorg-x11. Patch to fix this incompatibility supplied and should be applied to all ebuilds.

Created attachment 44368 [details, diff] glxgears-uclibc-gentoo.patch
Thoughts?
While the patch would work around the problem with current -rX of uclibc.. -rNEXT will include a more complete math library when build in not in USE= So not sure if this is the right fix (long term)
Could I get a status update?
Boostraped from stage1-x86-uclibc-2004.3.tar.bz2 in a chroot: >>> x11-base/xorg-x11-6.8.1.902 merged This is with sys-libs/uclibc-0.9.26-r8, i.e. -rNEXT form Comment #3. Yuri.
In that case, no need for this patch. Thanks for the report.
