This patch fixes various build failures seen with gcc 4.4
gcc prior to 4.6 complains about:
error: #pragma GCC diagnostic not allowed inside functions
for various uses of PUSH_IGNORE_WFORMAT and POP_IGNORE_WFORMAT.
This patch makes them a no-op with such compilers.
The patch also fixes various errors with template base initializers
and redundant uses of "typename" that older g++ implementations
can't cope with.
