I am trying to build octave on Sparc - Solaris-2.4
I am running GCC-2.7.0

I have configured the make with the following command:


CC=gcc ./configure \
	--with-f2c \
	--enable-dld \
	--enable-lite-kernel 2>&1 | tee conf-octave.history

the make process will fail with a compilation error in one of Octave 
modules:

I have edited the file DAE.cc and a couple of other files with the same
kind of problem and ran make again. This time GCC complained about some 
of class definitions and aborted the make.


Has anyone else had this problem with GCC-2.7.0 and Octave? Is there a patch
anywhere to correct this problem?
