Hmm.

I am not sure about these two cases:

1) cross (cross-tools)
configure --build=`config.guess` --host=i386-cygwin

2) target-native (`config.guess` := yyy, target-tools/libs)
CC=i386-cygwin-gcc configure --build=i386-cygwin --host=i386-cygwin

Further issues arise when installing *.[o|obj] files:
i.e. a compiler's chain's startup files or customized startup files
(a very common case for embedded systems).
