At first (untested)

#undef ASM_OUTPUT_ALIGN
#define ASM_OUTPUT_ALIGN(FILE,LOG) \
  if ((LOG) != 0) fprintf ((FILE), "\t.p2align %d,,7\n", LOG)

in gcc/config/i386/djgpp.h

Additionally we should add other needed alignment related macros 
into the same file (see gcc info file)

I don't think it's so complicated. 

Anyway cleaning contents of binutils-2.9.1.tar.gz from all 
unnecessary things (not needed for DJGPP) would require some
time. I myself have practically changed to binutils snapshots and
I'm building them from original sources with very small 
modifications. If putting binutils-2.9.1.tar.gz together with script for 
building binutils (patches embeded in script) would be good enough 
then it should not require much work.

My script should support both binutils 2.9.1 and also latest 
snapshots. Also if I run it for example under Linux I'm getting 
cross-binutils for DJGPP without any additional hacking.
