Thanks for the tip. We had one of the GCC developers look at the
problem (Eric Botcazou), and he found out that gcc-3.4.x is creating
some additional R/W ELF sections that the IRIX linker is not combining
(gcc-3.3.x created one R/W and one R/O ELF section). He plans to look
into this further. Hopefully we'll have a solution soon.
