Please repeat with configuring in directory different from source one

Cannot reproduce this. Tried with not modified gcc-3.0.2 sources:

../gcc-3.0.2/configure --target=i586-pc-msdosdjgpp --prefix=/usr \	
	--with-as=/usr/bin/i586-pc-msdosdjgpp-as \
	--enable-languages='c,c++'
make

and didn't get failure for libiberty. I had problem in libstdc++-v3 as 
configure incorrectly tries to use newlib specific files instead of
DJGPP ones. 

I suggest to apply patches from archive v2gnu/gcc302s2.zip You can find
in DJGPP distribution. Patches contain fixes for libstdc++-v3 configure 
for building DJGPP targetted cross-compiler and other fixes.
