Woohoo! :)

I agree libtool is probably not picking up on the change. Try something 
like CC="sparc-elf-gcc -mv8 -msoft-float" ./configure --target=sparc-elf
and see if that works better.

The GNU autotools generally have very poor support for cross-compilation 
though. It is probably worth just writing a custom makefile for it. Copy 
the list of relevent files from lib/(*/)Makefile.am and copy the 
relevent defines from config.h.in. You probably want:


I don't think the library requires any of the others.
