I didn't add any extra compiler options, beyond the default. I did use
the --enable-shared and --disable-static options, which were also used
in the octave-forge binary. Here is the compiler information for each:

For the octave-forge binary:
CC_VERSION = 3.2 20020927 (prerelease)
CFLAGS = -g -O2
CXXFLAGS = -g -O2 -Wall

For 2.1.50/53 from source:
CC_VERSION = 3.3.1 (cygming special)
CFLAGS = -g -O2
CXXFLAGS = -g -O2 -Wall

I noticed a few differences in other settings while looking through. I
can't say if or how these would affect the speed:

octave-forge binary:
LIBS = -lreadline  -ltermcap -lwsock32 -lm
SH_LDFLAGS = -shared

2.1.50/53 from source:
LIBS = -lreadline  -lncurses -lwsock32 -lm
MKOCTFILE_SH_LDFLAGS = -shared -Wl,--export-all-symbols
SH_LDFLAGS = -shared -Wl,--export-all-symbols -Wl,--enable-auto-import
