gcc-4.7.0-RC-20120302 fails to build for i686-pc-cygwin

[Ryan Johnson]

Hi all,

I tried to bootstrap the gcc-4.7 RC and it fails because it expects to 
find <process.h> and the file actually lives in <cygwin/process.h> (see 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52513).

I'm asking here because the gcc devs thought this would mean 4.6 is 
broken as well, but I have 4.6.2 running. Did process.h perhaps move 
between 1.7.10 and 1.7.11? I guess configure must be using linker rather 
than preprocessor tests for presence of spawnve, because it thinks 
(correctly) that the function exists.

Thanks!
Ryan
