Well, I got this backwards, so please ignore :-(

nor the C++ compiler (of egcs-971105) (Sorry, threw away the error  
message).  One of the first problems to be solved on  
m68k-next-nextstep3 is to have fixincludes repair  
/NextDeveloper/Headers as that directory is searched before all  
others (with the exception of /usr/local/include and the  
gcc-repaired directories.

To fill my copious spare time, I got egcs-core-971105 +  
egcs-g77-971105.  That combination built just fine and correctly  
compiled my 1300 routine Fortran application.
