That's pretty much vfork in a nutshell.

Most of libc.a is based on the free'd BSD sources.  Just make sure
it's the freed ones you're looking at, or we'll all have to pay AT&T
royalties.  Anything marked "public domain" or including an "as-is"
type copyright is OK for djgpp.  The problem is when GPL code is used
in such a way that it causes applications built by djgpp to become
GPL.  This has a habit of discouraging djgpp use for commercial
applications.
