I played around with this a bit, and found something rather amusing:

    sizeof(pid_t) ..... compiles just fine
    sizeof((pid_t)) ... parse error before `)'

The extra parens do it in. And this is with (an older version of) GCC:

    % gcc -v
    Reading specs from
/usr/bin/../lib/gcc-lib/powerpc-ibm-aix4.3.3.0/2.9-aix51-020209/specs
    gcc version 2.9-aix51-020209

This quirk might also be the cause of bug #47907.
