Thanks Carl.. passed along.

Regarding the original question of:
#if (!defined(__ICC) || __ICC > 1110) && AV_GCC_VERSION_AT_LEAST(4,3)
This is some feedback on versions:

The purpose of the construct is to provide as good of a check as possible
for code compatibility between ICC and GCC.  Depending on which version of
GCC and ICC you use the compilers are compatible but it is almost impossible
to maintain complete compatibility across all versions of GCC and ICC.



For more information on which compiler versions are compatible between ICC
and GCC see the following:
