It's certainly more efficient (but shouldn't it just be '2' for the 
second compare?) - if everyone agrees I'll make it a macro and use it
twice in the code.

Note: 2.03 uses strcmp an additional place in the FNCASE code - so you
can't easily eliminate strcmp there.

1) Create a completely separate working tree:
    cvs checkout -r v2_03_1 djgpp
2) Please don't commit anything unless we're sure we are building a
   new distribution (we want to keep the two consistent).  If we wait
   long enough we would need to branch v2_03_1 into v2_03_2 ;-P
