Created attachment 402378 [details, diff] Add -std=gnu90 to fix compilation with gcc-5 memtest86+-5.01 relies on C90 behaviour for linking and thus will not link with gcc-5. Apparently, the code uses also special GNU features, so that -std=gnu90 has to be added to the CFLAGS. Since the Makefile ignores passed CFLAGS, a patch (appended) is necesary.

That patch is still needed for sys-apps/memtest86+-5.01-r1 with sys-devel/gcc-5.2.0
Created attachment 407434 [details, diff] alternative patch for gcc-5.2.0
(In reply to Helmut Jarausch from comment #3) > Created attachment 407434 [details, diff] [details, diff] > alternative patch for gcc-5.2.0 Works with that patch. @base-system: Please add it the patch to the tree!
sys-apps/memtest86 (without plus) fails with same error too.
Can someone please push the fix above into the tree? This is the third build failure I encountered today, for which the patch is there but not pushed to the tree. Do we have shortage of gentoo devs in certain areas? Just curious. I haven't seen this abandonment of fixes before.
@base-system, is it OK to apply the first patch (--std=gnu90)? Looks like the sanest solution, as breakage is caused by default C std switch to gnu11. Works fine for me here.
i've fixed it w/out having to mess with the C standard: http://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e5b24d52ab056fffa21763d8a8ed09c04f4ce539
