+Subject: [PATCH] pkgconfig file must not have non -I flags
+
+The Cflags directive in .pc files is really meant for the
+preprocessor, not for the compiler. It must only contain -D and -I
+flags. Otherwise, it forces flags on downstream programs that may not
+want them.
+
+In case of the build.opensuse.org build farm, it has even led to
+crashes as the machine that was randomly selected to build givaro had
+SSE4, emitting -msse4.1 into Cflags, while the machine randomly
+selected to build fflas-ffpack had only SSE2. That cannot work.
+
+"Cflags: -I/usr/include  -fmessage-length=0 -grecord-gcc-switches -O2
+-Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables
+-fasynchronous-unwind-tables  -mmmx -mpopcnt -msse -msse2 -msse3
+-msse4.1 -msse4.2 -msse4a -mavx -mfma -mfma4 -mbmi -mfpmath=sse
