Title: [Q] cross-compile gmp lib for powerpc on Solaris





I am trying to compile the gmp lib for powerpc 860 / VxWorks on Solaris.  Got a few questions


Q1: What is the minimual version of gcc for powerpc support (I use egcs-2.91.66)?


Q2: How to setup gcc for cross-compilation?  I tried configure --target=powerpc-wvr-vxworks
      but the compiler reported the following errors for assemble files:


gcc -O2 -c -g -O add_n.s
add_n.s: Assembler messages:
add_n.s:29: Error: Unknown pseudo-op:  `.toc'
add_n.s:32: Error: Unknown pseudo-op:  `.csect'
