Bugzilla Bug 225079

While building fontconfig-2.6.0 this came up but I fixed it manually and
couldn't reproduce it.  Now it's here again!

output from emerge just after configure stage:

fcalias.h actually exists in fc-case/fcalias.h but no src/fcalias.h.  As a
workaround you can link/copy it to src/ and the compile completes. 
Alternatively I added this to src_compile:

src_compile() {
        CPPFLAGS="${CPPFLAGS} -Ifc-case/"
        ...

Can you reproduce this with MAKEOPTS="-j1" ?
How about for -j2?

I can't reproduce that with MAKEOPTS="-j2", but then, my computer is so old
that the only race it will participate in is the one to the junkyard...

meh... I can't reproduce it at all!  Same thing happened as last time: error
was there when I tried to upgrade, but doesn't reproduce when I remerge... 
configure output looks the same... hm will have to look more tomorrow.  any
hints?

:)  uuu-mah!

i read through the Makefile but couldn't find a race condition.  i also built
with infinite jobs and couldn't reproduce. :/

I think it's perhaps a one in a 1000 chance we've hit on here. It's been there
since at least 2.3.97, yet there's only three web references. The two above and
this one.

For description of the problem and patch take a look at:

https://bugs.freedesktop.org/show_bug.cgi?id=16464

I'll wait a bit for upstream to review my patch and then fix this problem in
our tree.

Thank you all guys. Patch was applied upstream and I've put it in our CVS too.
FIXED.
