xptcall port to sparcv9 with gcc3

Hello,

I have been trying to compile Mozilla 1.3 on a 64-bit Solaris 8
platform.  The compiler I'm using is a 64-bit gcc3.2.2 compiler.  I'm
running into errors in the build when regExport tries to link against
libxpcom.so.  The exact error is below:

../../../dist/bin/libxpcom.so: undefined reference to
`invoke_count_words'

I've been able to trace it back to the fact that sparcv9
with gcc3 hasn't yet been supported by xptcall.

I'd try to figure out how to do it myself, but I'm really more of a 
System Admin than a Software Engineer.  I'd be willing to help out with 
anybody who wants to do this and provide what other information I have.

Thanks,
Mike
