Please post about build problems in the octave-maintainers mailing list:
address@hidden
(I'm on nabble now so I can't delete the address@hidden address.
Please wipe that when you reply)

I suppose you're still on this thread:
  https://mailman.cae.wisc.edu/pipermail/help-octave/2012-August/053679.html

When building under MinGW using gcc 4.7.0 you are actually on you own,
sorry.
Nitnit has built Octave-3.6.3 using gcc-4.6.2, but unfortunately he still
hasn't published his build fixes.
I'm still using gcc-4.5.2, and with some fixes described here:
 
https://mailman.cae.wisc.edu/pipermail/help-octave/2012-September/053786.html
I could build Octave-3.6.3.

>From what I can see you may have some includes missing and/or gnulib issues;
remember MinGW is not (yet?) fully compatible to Linux. In the past I could
get through various build errors by googling around for solutions outside
the Octave MLs.
