Given your setup is OK, and according to your report it is, it may be 
you hit a limit concerning the way debugging info is stored
inside the COFF format. AFAIK only 64k debugging symbols are possible.
The workaround would be compiling some modules without debugging
information, and add -g only to those you want to investigate. 

The solution is to search the mail archive on 
www.delorie.com/djgpp/
for ``stabs'' , search for a kind soul that patched
gcc (?) and the binutils (?) for supporting the stabs-format. 
I think Robert has done something like that, but I'm not
sure.

No, unless you have a typo here. 60kB x 8 are merely 256kB, something
that every computer nowadays should have free. FWIW, post what RHIDE
spits
out when you create a bug report.
