Ahhh... you fell foul of a previous hack of mine! :-)

Yes, so don't worry about it. The 2.1.14 tree is compiling fine like this.

Are you sure you want to link it as high as 0x80100000?? Even the DECStation
only steals 192K of memory down low...

Yes, this is probably just a problem in your ld.script.

No - what object format are you compiling to? I now leave all intermediate
object files in elf and specify ecoff-littlemips to the linker as the final
