This might explain how it works for me: I manually edit config.h to
convert MSYS file names to native Windows ones, before building GDB.

Perhaps Joel could tell where and how the relocation of the standard
directories happens for him, and then we could try stepping through
that code with a debugger.

A simple Sed script will do, but it must be injected into the
configure script.

Alternatively, did you try to use MinGW file names in --prefix when
configuring in the first place?
