 This was wrong; This happened simply because the pragmas push_macro and
 pop_macro are not implemented on the tested compilers. After updating gcc
 from 4.4.1 (!MacPorts) to 4.4.5 (!MacPorts), "test.mm" gets successfully
 compiled with r66143.
 However, with r66289, compiling "test.mm" using !MacPorts gcc 4.4.5 fails
 again (see below).

 Comments about r66289, [[BR]]
 !MacPorts gcc's are non-apple compilers, but they seem to have
 !__APPLE_CC!__ macros.
 While !__APPLE_CC!__ is defined as 1 in !MacPorts gcc's,
 Apple gcc's define !__APPLE_CC!__ as the build numbers (e.g. 5488 and
 5564).
 So it might be better to use
 {{{
 !(defined(__APPLE_CC__) && __APPLE_CC__ > 1)
 }}}
 for detecting non-Apple compilers.
