Hello,

Over on gentoo, our packaging of xv is showing some QA check failures, it is catching compiler warnings:

QA Notice: Package triggers severe warnings which indicate that it
may exhibit random runtime failures.
/var/tmp/portage/media-gfx/xv-6.0.0/work/xv-6.0.0/src/xvjpeg.c:510:36: warning: variable ‘colorspace_name’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Wclobbered]
/var/tmp/portage/media-gfx/xv-6.0.0/work/xv-6.0.0/src/xvpng.c:434:21: warning: variable ‘numuniqcols’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Wclobbered]

I checked a couple more versions, 5.2.0 shows the same warning, 3.10a does not.
