I was trying to compile a DJGPP gcc 3.0 cross compiler from linux to dos 
but I get this error:
---------------------------------------------------------------------
/root/src/gccdos/i586-pc-msdosdjgpp-gcc/gcc/xgcc
-B/root/src/gccdos/i586-pc-msdosdjgpp-gcc/gcc/

this function)
../../../gcc-3.0/libiberty/getpwd.c:74: (Each undeclared identifier is

make: *** [all-target-libiberty] Error 2
---------------------------------------------------------------------

Checking the preprocessor output I found that the problem is that 
the include /root/src/gccdos/i586-pc-msdosdjgpp-gcc/gcc/include/limits.h
is used instead of the include (from djcrx203)
/usr/local/gcc-3.0-i586-pc-msdosdjgpp/i586-pc-msdosdjgpp/include/limits.h

My gcc-3.0 config.status is:
---------------------------------------------------------------------
../gcc-3.0/configure 
--with-gcc-version-trigger=/root/src/gccdos/gcc-3.0/gcc/version.c
--host=i686-pc-linux-gnu --target=i586-pc-msdosdjgpp
--prefix=/usr/local/gcc-3.0-i586-pc-msdosdjgpp -v --enable-languages=c,c++
--disable-nls --norecursion
---------------------------------------------------------------------

The make command is :
make -C gcc installdirs


How can I solve this ? 
I already solved it manually for the libiberty library, but I'm unsure
of the confidence of the resulting compiler.
