Here is an example where the answer depends on your situation.  If
you have a bunch of OLE libraries, etc. there is no problem linking
with them.  Currently you just have to supply the 3rd party (ie. MS)
C library.  The response was intended for folks trying to "get by"
with just the free GNAT package.  Until all of the Cygnus libraries are
integrated with GNAT, you'll have to link with your own LIBC.

This is available:  Cbind does this.

True.

Agreed.
