# Note to self: don't use the Makefile, it just runs setup.py but
# doesn't give us a way to pass options to it.

# sed surgery: setup.py allows overriding the compiler flags, but
# puts a -O3 *after* whatever we set them to. All our SLKCFLAGS
# choices have -O2.

# The -Wl,-s makes the linker strip the binaries.
# --ignore-compiler-warnings is needed to turn off -Werror.
