Hmm... nope. In fact, that got stuck too. 'ls /proc/2072' dies and must
be 'kill -9'd. 'ps | grep 2072' says:
PID PPID PGID WINPID TTY UID STIME COMMAND
2072 1 1876 2072 con 1003 Apr 21 /usr/bin/bash
'ls /proc/<pid of cl.exe>/fd' failed to revive it. If I cat it's cmdline
(in its /proc), I see that it matches what 'make' is claiming it ran.
Something a little suspicious(?); fd's 5-7 are all pointing at the same
place and that place is a directory. Also, 255 is pointing at the shell
script (/w32dev/cl32.exe) that launched (exec()'d) the process. If it's
relevant, 'make' (which does show up as the parent) actually launched
'cl'; it exec()'d through 3-4 scripts to get to the actual binary.
