Invoking v2 programs from Emacs 19.30 is dangerous and should be done, if 
at all, with extreme care.  The reason is that v1.x programs cannot spawn 
v2.0 programs (the v1.x spawnXX code sees the COFF signature in the v2 
executables and tries to run it with go32, which either crashes or 
silently fails).  `M-x compile' should work most of the time, though, 
because it runs the command with `command /c', not directly.  But 
nevertheless I've seen all kinds of weird behavior in that setup (and you 
don't tell enough in your message to analyze your specific case).

I have seen enough of such trouble to the point that I don't take
seriously any problem of the above kind when v1 programs are used to 
invoke v2 images.  My advice: switch to v2 (Emacs 19.31 will support v2, 
and you can get the latest pretest if you can't wait.)
