Problem building 4.2.0 on Solaris 10 (SPARC)

[Luke Dalessandro]

I'm trying to build on:

   Sun-Fire-880

I've configured with:

   --prefix=... --with-as=/usr/sfw/bin/gas --with-gnu-as --with-ld=/ 
usr/ccs/bin/ld --without-gnu-ld --enable-languages=c,c++ --enable- 
shared --enable-tls --enable-threads=posix

The build command that I am running is:

   make BOOT_CFLAGS='-g -O3' -j 8

The problem that I am having is (I've manually changed the path to a  
relative path from where I ran 'make'):

   make[2]: Entering directory `../gcc-4.2.0'
   make[3]: Entering directory `../gcc-4.2.0'
   rm -f stage_current
   make[3]: Leaving directory `../gcc-4.2.0'
   Comparing stages 2 and 3
   /bin/sh: stage3-gcc: does not exist
   make[2]: *** [compare] Error 1
   make[2]: Leaving directory `../gcc-4.2.0'
   make[1]: *** [stage3-bubble] Error 2
   make[1]: Leaving directory `../gcc-4.2.0'
   make: *** [all] Error 2

stage3-gcc exists in the subdirectory:

   host-sparc-sun-solaris2.10

Can anyone tell me what I am missing here?

Thanks in advance,
Luke
