I tryed to compile gcc-2.7.2.2 with g77-0.5.20 on my pmax.
I'm running this pmax with the stuff of snapshot-1997-05-01.
I tryed several different compiler options as 
-mno-abicalls -mno-half-pic
-fpic -fPIC ...
(I'm not that much used to compile compilers ).
Ok, the usual problem was this:
 .. ld: .. can't link PIC with non PIC files ..
or something like this.

Who can help me? - The person who compiled the gcc of the
snapshot-1997-05-01 should perhaps know how things work and
which CFLAGS etc. he/she used.
