Here's the deal for 64 bit Linux as far as I have tested it (OpenSuse 11.2):
The gcc2 tool chain cannot be built in a 64 bit environment, so one has to
use linux32 when running ./configure --build-cross-tools [...]. Other than
that there are no restrictions. The gcc4 build can be configured with or
without linux32 and/or with or without --use-32bit. Both gcc2 and gcc4 build
can be jammed with or without linux32, regardless of how they have been
configured.
The problem in #5191 was apparently just that the wrong jam was used.
So, essentially --use-32bit is superfluous under Linux. I don't know if it
does anything for other platforms.
CU, Ingo
