Not really.  This way should be taken only as desperate measures, when
you have no access to the sources of the compiled libraries.  The
chances of success are usually slim.

It depends on what non-standard extensions your programs use.  If you
tell a few more details about the programs, it might be possible to
come up with a more concrete answer.

Try Chapters 18 and 17 (in that order) of the DJGPP FAQ list
(v2/faq211b.zip from the same place you get DJGPP), and then ask
specific questions if the FAQ leaves something unclear.

It is both possible and practical.

Check section 22.3 of the FAQ, it mentions a few of them.
