The problem is not gcc4, but its use of modern C++ code in the libstdc++
library headers (notably the type_traits, I believe), which occ doesn't
parse correctly.

The above error, however, seems to stem from system headers, notably
some inline assembler code, which, IIRC, should be skipped by the lexer.
