The right thing to do is what the building guide says.
The GHC build system is careful to use the newly-built GHC for compiling
even .c files, and for doing linking. The newly-built GHC will use the
gcc that you point to with the --with-gcc configure command. It will not
use a path in any shape or form (unless you omit --with-gcc in which
case it'll pick whatever random gcc is lying around; probably not the
right one).
The only way I know to make all this work is to use a straightforward
Cygwin environment for building (with absolutely no mingw stuff in your
path) and use --with-gcc in your configure line. Other things may work,
but you're on your own.

| |
| | export PATH=/cygdrive/c/lang/mingw32/bin::${PATH}
| |
| | make clean; ./configure --build=mingw >& configure.log
|
| Uh oh. You aren't following the instructions in Section 12.4 of the
GHC
| building guide!

|
| (a) I believe that it's important to run autoconf
| (b) I've never seen this --build option for configure. What I use (as
| the building guide says) is:
|
| ./configure --host=i386-unknown-mingw32 --with-gcc=/mingw/bin/gcc
|
| You need to run configure in fptools/ghc first actually. (No need to
| autoconf there.)
|
|
| What you did may work, but I am not confident in it. For example
where
| are you saying where to find the (mingw) gcc that GHC should use?
