gdb-4.18 is extreemly old. Even gdb-5.0 is old for use with
gcc-3.0.X. Unfortunatelly gdb-5.1.1 is not released
yet for DJGPP.

Make sure You have binutils new enough. Latest update of 
binutils-2.11.2 for DJGPP is required to use DWARF2 debugging
info (I myself am using newer CVS version of binutils for most stuff,
but 2.11.2 for building GCC itself)
