Subject: build: issue #41 builds without mmx/sse etc extensions do not work
X-Git-Tag: archive/raspbian/1%0.1.106-3+rpi1^2~15^2~11^2~37
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=030303d8c1528232efba1f6ac9425352903764df;p=babl.git

build: issue #41 builds without mmx/sse etc extensions do not work

The warnings about the SIMD flags specific variables not being set goes
away with this commit. Setting empty strings do not work since then gcc
ends up looking for input files that are the empty string, thus this patch
re-adds -Wall instead of setting an empty string.
