Even though Bruno's pipe module is generally a better interface than popen, I discovered yet another popen bug in cygwin today[1] (I fixed a cygwin popen bug in August 2006, only to have it regress in December of that year when cgf rewrote the implementation to be faster). So even though m4 no longer uses popen, I'm at least going to write a popen replacement module, and wondering if I should also add popen_safer in the process.
