64bit phobos on Windows?

[Andrej Mitrovic]

I'm sorry for hijacking this topic guys. :p

I am getting somewhere though. GDC changeset 475, using GCC 4.5.0 with
applied TDM-GCC 4.5.0 patches, with built gmp, mpc and mpftr. The
Windows build documentation needs an update (I'll fix it myself given
the chance).

I've gotten build errors after:
make STAGE1_CFLAGS="-g3 -O0" 2>&1 | tee build.log

this time its Phobos:
../../../../gcc-4.5.0/libphobos/rt/fpmath.d
../../../../gcc-4.5.0/libphobos/rt/fpmath.d: In function 'signbit':
../../../../gcc-4.5.0/libphobos/rt/fpmath.d:1:0: internal compiler
error: in build_ref_for_offset_1, at tree-sra.c:1405
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bitbucket.org/goshawk/gdc/issues> for instructions.

I guess I should file a bug report with the full log.
