Log:
[MSVCRT][CRT]: Improvements/fixes over popen(), from Wine code and ported by
Andreas Maier: the popen_handles array, which is used in _pclose, was never
filled. _popen correctly fills it now.
Should fix returned codes by popen() and pclose(), which are functions that are
called by windres, and this latter expects them to succeed. This was not the
case before, in ROS, and therefore
trying to e.g. compile ROS within ROS failed from time to time with windres
throwing the error that "preprocessing failed".
