No. The first part was the same, but the header Pascal posted had an
*exception* at the end. That's the important part. That part allows users to
compile against those packages without the resultant executable being GPL.
The extra text at the end which you missed is the following (cut from the file
header in GNAT/lib/gcc-lib/pentium-mingw32msv/2.8.1/adainclude/g-spitbo.ads):
-- --
-- As a special exception, if other files instantiate generics from this --
-- unit, or you link this unit with other files to produce an executable, --
-- this unit does not by itself cause the resulting executable to be --
-- covered by the GNU General Public License. This exception does not --
-- however invalidate any other reasons why the executable file might be --
-- covered by the GNU Public License. --
-- --
Just add this paragraph to the end of your GPL notice in the file headers and
you'll be ok.
If you copy a file header from the source code for the compiler itself, rather
than one of the packages inteded for a *user* of the compiler, I would expect
you to not see this paragraph. That helps prevent anyone from building a
prorietary compiler on the free work done by others.
T.E.D.
