Request of clarifications on GPL license

[Marco Maccalli]

Dear Sirs,

a client of ours is interested in using GCC in order to compile a 
proprietary application that they are currently developing. We would 
like to have a better understanding of the implication on the 
proprietary nature of our client's application related to the use of GCC 
and its associated libraries. We understand that GCC uses libraries 
available under GPL license (and not LGPL) and we would like to 
understand whether there is a risk that these GCC libraries may bring 
our client's application also under open source rules.

We would be grateful if you could help us in clarifying the above and/or 
provide any guidance on how to be able to keep our client's application 
proprietary and "closed source".

Thanking you in advance, we remain,

Yours Sincerely,

Marco Maccalli
