I am still confused. Does mere linking make the result realy
code from a GPL program?

For example, if you go to
<> ,
download and install lccwin32.exe and look in its "lib" folder, there
is a gdbmdll.dll library, yet the package neither is GPL nor are the
sources publically available.

Now go to
and click through and download lccdist.tar.gz. In the "bin" folder
there is a "lcc" program that requires, the
same folder contains a binary, yet the package
neither is GPL nor are the sources publically available.

How come they are allowed to do that but I am not?

Again, is mere dynamic linking the same as "incorporating GPL-covered
