+# - don't assume 'cc -n32' if the n32 libm.so is missing
# Use sh Configure -Dcc='cc -n32' to try compiling with -n32.
# or -Dcc='cc -n32 -mips3' (or -mips4) to force (non)portability
# Don't bother with -n32 unless you have the 7.1 or later compilers.
# But there's no quick and light-weight way to check in 6.2.
