NO! If all the libc.a functions were linked into every image each exe
would equal 400+K! Only the ones neede for the particular image are
loaded as per usual. There is however some functionality that can be
discarded. Filename globbing is an example (ie expansion of wildcard
arguments). Check the info files for the crt0 startup flags. These can
be used to reduce the file size.

Basicly it is always a good idea to read the FAQ and if possible to
search the mail archives on http://www.delorie.com/djgpp/ ...

If you haven't already got the FAQ then get faq200b.zip from where you
got v2.

I'm sure it's in the FAQ.
