Hi,

With pacman-4.1 we introduced CPPFLAGS in makepkg.conf and moved the -D_FORTIFY_SOURCE=2 flag out of C{,XX}FLAGS to there (where it should be).

This of course will break wine's builtin workaround for FORTIFY_SOURCE, which assumed that it was in CFLAGS. Maybe no matter as for some reason it wasn't working on archlinux in any case.

It produces the following (snipped from the gcc output) -D_FORTIFY_SOURCE=2 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0, which for some reason seems to produce broken code.

This also breaks 'crash' AUR package. I workaround' the issue by 'unset CPPFLAGS' before building the package https://aur.archlinux.org/packages/crash/ https://gist.github.com/anatol/5326430
