Why is BinUtils 2.17 so much bigger in .EXE size than 2.16.1?? I'm not
trying to be a pedant, I'm just curious why it's 5x the size of the
previous version (15 MB vs. 3 MB). Any obvious reason anyone know of?
P.S. Good to hear that link times are decreased. In fact, I'd love to
hear more such rough benchmarks from people regarding various DJGPP
tools. (Anyone??)
