   Yes, but of course it would link with their libraries since it uses
   their standard functions (i.e. even 'printf' is part of a GNU library
   with GCC).

Use of GCC does not a priori mean you are using a GNU printf().  GCC
uses the vendor's libraries (which is why GCC doesn't always provide
an ANSI C library) rather than supplying its own.

For example, on a project I worked on last year, we used GCC to
compile the application, linking with several vendor's libraries (like
Sybase and XVT and such, as well as SunOS).  No GPL problems at all.

Now, had we installed GNU libc (glibc) and linked with that, we would
have been subject to the LGPL that glibc is distributed under.

Also, some system are distributed with glibc (or a variant) as their C
library, and if you hope to distribute commercial (read: proprietary)
software on such platforms you had better be linking dynamically.
