Avoid spurious GCC warnings in STATIC_ASSERT() macro.
GCC 4.8 now warns about typedefs that are local to a scope and not
used anywhere within that scope. This produced spurious warnings with
the STATIC_ASSERT() macro (which used a typedef to provoke a compile
error in the event of an assertion failure).
This patch switches to a simpler technique that avoids the warning.
v2: Avoid GCC-specific syntax. Also update p_compiler.h.
