Build 21.0 on M88K DG/UX

I'm trying to get Xemacs to build on DG/UX using the GCC that is supplied with the O/S. I have made a few minor modifications to configure and some header files. I've run into one more problem with configure and/or the Makefiles and I cannot figure out how to create a reasonable correction. The problem is that libgcc.a is assumed to be at /usr/lib/gcc/libgcc.a. Unfortunately, DG has decided to put it at /usr/lib/libgcc.a. The command gcc -print-libgcc-file-name returns the correct location, but apparently configure does not use this for DG/UX. How could this be corrected? david
