Compiling vim on Windows using mingw with debug symbols

[Christian Brabandt]

Hi,
until recently, I could successfully build and run gvim for Windows
using mingw.

But today I noticed, I can build a debug build of vim, using mingw, but
it won't run. Gvim does not even startup. When running under gdb, I get
this error:

Does anybody knows what happened or how am I supposed to compile a
windows version with debug symbols built in, that works?

For the record, this is a win7, 64bit system.
