When `dosexec' looks on the PATH, it only tests for file's existence, not
if it's at all executable.  This might cause some grief to innocent users. 
A case in point is when you try to use the port of GNU `install'.  If you
try to invoke it from a Makefile of any of the GNU packages, you will
immediately crash, because these packages come with a text file called
INSTALL ...

I think it's appropriate to change the calls to `access' inside 
`__dosexec_find_on_path' and `__spawnvpe' so that they test for X_OK.  If 
nobody objects, I'll submit the patches.
