To "make" correctly version 4.2.2 you need to "make install" previous version
of built compiler (/cygwin/usr/local/bin), but not lower than 4.1.0. Compiler
complains on unrecognized "-Wc++-compat" which uses in makefile and which seems
appeared in the 4.1.0 version.
I think this is bug because in "Prerequisites for GCC" nothing said about this
kind of requirement.
