MinGW compile problems

[Parker, Joel J. K. (GSFC-5950)]

Hi all,

I'm attempting to compile Octave straight from the Hg repository on Vista/32 
using MinGW/GCC 4.5.0. I've successfully gotten through the autogen.sh and 
configure steps, but I'm getting a gnulib-related compiler error during the 
make step.

Here's what I'm seeing:

<...>
libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I.. 
-I/c/Users/<name>/Software/gnuwin32/include -I../libgnu -I../libgnu

make: *** [all] Error 2

I see no errors during the autogen.sh step, and configure completes 
successfully with warnings about missing libraries for optional behavior (I 
haven't filled these holes yet).

Any ideas?

Thanks,
