Wasn't it 29-Jul-2002, at 02:31PM, when Marlin Unruh said:

No compiler is "standard" (I'm assuming he's not talking about language
standards.) If he's looking for a popular compiler though, GCC is very
popular since it has been ported to many processors and platforms. I've
used GCC, for instance, to build applications for i386-FreeBSD,
i386-NetBSD, m68k-PalmOS, AVR, PowerPC-VxWorks, and i386-Linux machines.

Actually, your partner's "facts" are really just his opinions.

If you are the primary developer and have used the compiler for a year and
you feel, with your experience, that AVR-GCC can do the job, what other
reason does he need? Buying a commercial compiler would require you to
familiarize yourself with the new tools which would make you less
efficient. Learning the strengths and weaknesses of a compiler takes time.

Also, what commercial compiler can respond to bug fixes as fast as Marek
does? What commercial compiler has a forum, like this one, where people are
polite and quick to help out?

The only thing I can't comment on is how well GDB helps in debugging an AVR
application. From what I've read on this list, it shouldn't be a problem,
but I have no direct experience with it.

Hope this helps! Good luck!
