Query about GPL-license

[Tom Womack]

I know that the output of GCC is not covered by the GPL because libgcc.a has
a specific exemption.

Could you confirm that the same applies to the output of G++ when I'm
compiling STL code (so including lumps of templated stuff for map<foo,bar>,
as well as libstdc++ to get iostream working right)?

Linking libstdc++ does not infect your code with the GPL.  libstdc++'s
components have license clauses which prevent infection.

Even though this question has been answered, I'd like to point out two
problems in your question.

First, it was sent to gcc@gcc.gnu.org, which is the list discussing
further development of gcc; if you need help with using gcc, please
send the questions to gcc-help@gcc.gnu.org.

Furthermore, please try to familiarize yourself with reading licenses,
instead of asking for permission everytime you want to use something.

In the specific case, if you would have looked at stl_map.h, you'd
noticed that it reads

So you got permission to use this software from both HP and SGI - you
don't have to ask us for permission.

Performing a similar investigation for the iostreams code is left as
an exercise to the reader :-)
