  I had no problems building the RC using:

binutils             2.22.51-1
cygwin               1.7.9-1
gcc4                 4.5.3-3
gmp                  4.3.2-1
make                 3.82.90-1
mpfr                 3.0.1-1

  Right, I think this is a cygwin bug.  The /usr/include/cygwin dir is private,
you're not supposed to #include files from there directly, they should be
indirectly included from within other system header files.  If process.h is a
public header, it shouldn't have been moved there.

  Ah.  In fact, I see from the reply to your email there that it is indeed an
acknowledged error in 1.7.10 and fixed already in 1.7.11.  Since the .10
release was buggy in several other important ways, I don't think it's important
to support it, we'll just tell people they need to upgrade.  Closing as
WONTFIX.
