Build GCC 4.1.2 with ECJ 1.4

[Sunil Amitkumar Janki]

I am trying to build OpenOffice.org on 32-bit little-endian
MIPS and (big-endian) SPARC. To make wizards and other
things work I need a JDK 1.5 compliant GCJ/ECJ.

I would like to know if there are any directions on how to
build GCC 4.1.2 with ECJ 1.4 as the default or an additional
Java compiler.

I will also try the latest GCC 4.3 snapshot but I prefer (tool
chain) stability over the latest and greatest.
