Thanks Ian. http://wiki.osdev.org/GCC_Cross-Compiler suggested --enable-languages=c,c++ --without-headers --disable-nls but that made no difference. So I gave the target a symbolic link to /usr/include, and then it failed in linking because of missing object decks. Seems like the process is building something I didn't ask for, or at least do not want. What I am after is in fact a cross compiler to s390 os/360 object (well, the variety that supports long ESD names--and not the old MVS attempt.) As I already have a cross assembler, I guess I should simply take the intermediary xgcc and run. I did come across crosstool in my googling, as well as a number of sites bemoaning the quality of documentation of gnu cross compiling.
