I have just compiled groff 1.08 on my 486 PC using gcc 2.5.7 an djgpp 1.11.
It seems to work OK, but I'm still doing some tests.

I found a possible bug in gcc 2.5.7 (or is it djgpp) with sscanf :
sscanf should return the number of items scanned succesfully, but it
seems to return -1 instead in a few cases, e.g. :

returnvalue = sscanf (my_string, "%d-%d", &lower, &upper);

with my_string = "10-100" the returnvalue is 2 --> OK
with my_string = "10 " the returnvalue is 1, while lower contains 10 --> OK 
with my_string = "10" (no space after 10) the returnvalue is -1, while
lower contains 10 --> BUG ??

A few routines in the groff package expect the returnvalue to be 1, so they need to be changed a bit to make them work.

If you're interested, I'll send the makefiles somewhere this week
(don't have them here).

Regards,
Tim
