[Vorbis] compile error

[Jim Worrall]

I've been trying to figure out for a couple of days why I can't get libvorbis to compile.  It has me stumped, though I'm not a whiz at compiling from source.

I'm installing on Mac OSX 10.8.2.  The relevant commands are:

export CC=clang
./configure --prefix=${TARGET} --build=x86_64 --with-ogg-libraries=${TARGET}/lib --with-ogg-includes=${TARGET}/include/ --enable-static --disable-shared --disable-oggtest && make -j 4 && make install

This error shows up 3 or 4 times:
configure:12338: clang -o conftest -O20 -Wall -Wextra -D__NO_MATH_INLINES -fsigned-char  -DUSE_MEMORY_H   conftest.c -lpthread   >&5
error: invalid value '20' in '-O20'

config.log is attached.  I would really appreciate some pointers on what I am doing wrong.  Thank you.
