help with porting texmacs to mips ?

[Ralf Treinen <treinen@debian.org>]

Hi, the texmacs package does not compile on mips[el]. The autobuilders
bail out with message

/tmp/ccQouOpD.s: Assembler messages:
/tmp/ccQouOpD.s:2744: Error: Branch out of range
/tmp/ccQouOpD.s:3563: Error: Branch out of range

A complete build log can be found at

http://buildd.debian.org/fetch.php?&pkg=texmacs&ver=1.0.0.17-5&arch=mips&stamp=1035698277&file=log&as=raw

When I asked for help on this list earlier this year, someone suggested
to me to try gcc>=3.0. However, upstream told me that this is currently not
an option sine on gcc3.2 optimization would have to be disabled.

David Allouche, one of the upstream developers, wrote to me about this
problem:

Does this make sense to you? Can anyone of this list give me an advice
what to do?

Thanks in advance -Ralf.
