optlink options to reduce file size?

[simendsjo]

A simple hello world like dfl application takes 1.2mb. Upx does a great 
job packing this to 200k, but I wonder if there is a way to make optlink 
generate smaller executables?

I couldn't find a way to get help on the numerous options in optlink, 
and the help page at digitalmars doesn't list them either.
