| This patch does solve the problem. Octave compiles and installes,
| however:
| 
| 1. Compiling with gcc 2.95 doesn't seem to like std::bad_alloc
|    (in libcruft/misc/quit.h). I removed it to get it to compile.

Can you send a copy of the error message?  It doesn't seem to be a
problem for 2.95 on my Debian system.

I have upgraded my Cygwin system to use gcc 3.2 so I did not try to
reproduce this problem with gcc 2.95.  With 3.2, everything seems to
work properly with the current sources from CVS, and I can use
mkoctfile to build .oct files.
