I don't know if the information I sent out reached you. My copy of the 
message appears corrupted. Please ignore this message if my previous 
message was recieved intact.

The byte counts for go32.exe using "dir" is 78826
                    gcc.exe              is 79872
                    cc1.exe              is 1098240

The core files are attached. The programs which were run are (in order of 
core dumps) are:
gcc -v
gcc
