Compiling programs licensed under the GPL version 2 with GCC 4.4


Kalle Olavi Niemitalo discovered that as an operating system vendor,
you are not allowed to distribute GPL version 2 programs if they are
compiled with GCC 4.4.  The run-time library is GPL version 3 or
later, which is incompatible with GPL version 2, so it is not
permitted to link this with the GPLv2-only program and distribute the
result.  (Previous discussions have centered on infringing GCC's
license, so this is different.)  An operating system vendor cannot
make use of the system library exception in the GPL version 2; this
part is quite similar to the OpenSSL and former Qt situation.

According to Kalle, this is [gnu.org #433709] at the FSF.

What shall we do about it?  Any solution without support from the FSF
will result in circumventing the restrictions imposed by the new GCC
library exception.
