I guess it would be easier to see changes from:

ftp://ftp.delorie.com/pub/djgpp/rpms/djcross-gcc-4.8.0/djcross-gcc-4.8.0.tar.bz2

Its much smaller and contains only DJGPP related patches and scripts
for using them. Changes from subdirectory diff2 in that archive are not needed
for building cross-compiler only ones from subdirectory diffs.

One may also try SRPM from the same place:

ftp://ftp.delorie.com/pub/djgpp/rpms/djcross-gcc-4.8.0/djcross-gcc-4.8.0-1ap.src.rpm

This fix is required for current stable version (2.03) of DJGPP only. I only built for
development version 2.0.4 (really recent once from CVS) which does not need this fix.

Native build for DJGPP v2.03 fails due to DJGPP own problems and was left out
for that reason and because of DJGPP v2.03 is already too old.
