Hi,
I'm trying to build a Cygwin cross compiler (i.e. a compiler that runs
on Linux but generates binaries that run on Cygwin)
For this, I tried to follow the instructions at
http://x.cygwin.com/docs/cg/prog-build-cross.html
However, these seem to be obsolete.
Indeed, on my Fedora Core 5, I get the following error when attempting
to configure gcc:
*** This configuration is not supported in the following subdirectories:
target-libffi target-boehm-gc target-zlib target-libjava
target-libf2c zlib fastjar target-libobjc
(Any other directories should still work fine.)

*** The command 'gcc -o conftest -O2 conftest.c' failed.
*** You must set the environment variable CC to a working compiler.
Is there any more up-to-date version of these instructions online?
Or, even better, some pre-made RPMs of a cygwin crosscompiler?
Thanks,
Alain
