Hmm, I'm now trying to rebuild OSlib in AOF mode and having toolchain issues
in DefMod2 (today's SVN 5844):


/local/scratch/atm26/riscos/autobuilder/oslib/!OSLib/Source/../Bin/defmod -asmtype gccaof -h < CDFSFiler.swi > CDFSFiler.h
/local/scratch/atm26/riscos/autobuilder/oslib/!OSLib/Source/../Bin/defmod -asmtype gccaof -h < NetFiler.swi > NetFiler.h

I can see why this is happening; in AOF mode DefMod2 is compiling a command
line that includes 'gcc' but that's picking up the system gcc not the cross
compiler. It appears the paths from ro-make aren't getting through - if I
change the DefMod2 source to call arm-riscos-unknown-gcc instead, it can't
find it.

I don't fully understand how passing through path variables works... any
suggestions?

Thanks
Theo
