The problem was that it caused relative prefix detection to errorously
use it (not harmfull through). I added small piece of code in gcc/gcc.c
to convert DIR_SEPARATOR_2 to DIR_SEPARATOR when first 
is defined in latest update of DJGPP port of gcc-3.0.2

Verified that it fixed this small (and mostly cosmetical) problem.
