Dear maintainer:
During a rebuild of all packages in unstable, your package failed to build:
cd zfifo && make
make[5]: Entering directory '/<<PKGBUILDDIR>>/src/libmawk/regression/zfifo'
cp ../../zfifo.c .
cp ../../zfifo.c .
cp ../../zfifo.h .

cp: cannot create regular file './zfifo.h': File exists

dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
Looks like a race condition where one make thread tries to create zfifo.c and another
make thread tries to create zfifo.h at the same time.
I'm not sure about the "file exists" error. Maybe it happens because the file zfifo.h is still
open by the first thread when the other tries to copy the same file.
I agree this is odd, because the package has not changed in a long time,
but I'm currently doing archive rebuilds with Intel machines (a little bit faster)
and I was able to reproduce this several times in a row (I can offer a VM to test
if you need it).
To fix this, I propose just splitting the target in two, one for zfifo.c and one for zfifo.h,
as in the attached patch.
Thanks.
