[mythtv-users] mythtv 0.24-rc will not compile with gcc 4.7

[Kevon]

Anyone have any luck compiling myth with gcc 4.7? I just upgraded and
everything seems to be broken. First it was ffmeg where h264_qpel_mmx.c
needs to be patched, which I managed to fix. Now I'm stuck on compat.h
in libmythbase. Nothing seem to be picking up unistd.h from compat.h.
Everything which requires a function from unistd.h fails. When I add
unistd.h directly to the .cpp  file, it compiles fine. What am I missing
here?
