* sigproc.cc (pending_signals::clear): Yet another fix to fix the fix.
Actually iterate over the list of pending signals even if there's a
signal which doesn't have to be cleared. Other than that, revert loop
to it's former self as a while loop.

This fixes a long-standing problem when GetProcAddress fails
to load a function. The noload code calls SetLastError on
i686 without saving the edx register. Starting with Windows 7,
SetLastError apparently uses $edx and the register is set to
0x00000000 on return. So the subsequent `jmp *$edx' in noload
supposed to return to the caller, actually jumps to address NULL,
which results in a SEGV.
* autoload.cc (noload): i686 only: Save and restore $edx when calling
SetLastError to avoid clobbering return address stating with Windows 7.
