+OS/9? I want to run the compiler on an HP-UX system, and generate
+loadable modules for OS/9 (running on a 68k). Are there any pitfalls

The 'as delivered' GNU package does not support 'OS-9'. The reason
is that the gcc package outputs files in BSD style a.out format(with
some number of variations on that theme) and doesn't directly
support accessing program variable via a base register.

OS-9's module scheme requires that programs be 'PIC' and use an
address register to point to a region of memory, offsets from which
correspond to the program variables.

There is some features, which I have not investigated yet, in 2.1
which allow for 'PIC' code to be generated but I have not seen
anything for the register based variable problem. There is a
'native' port of gcc to OS-9 available on an archive site named,
"smilodon.cs.wisc.edu". This generates assembler code which is then
fed into the OS-9 native R68 assembler, and subsequent output to the
OS-9 linker.
