If you're asking about /bin/bash or /bin/sh, then, no, they don't recognize
.com or .bat extensions, and so, you're required to specify the extension
specifically. The Cygwin DLL treats .exe specially such that when you
do an ls -l on a .exe file you don't need to specify the .exe, i.e.,
ls -l /bin/pwd
and
ls -l /bin/pwd.exe
are equivalent. This means that bash can find a pwd in your path and execute
pwd.exe.
Cygwin doesn't provide this for such things as .bat and .com files, since IMO,
this would slow things down for little gain.
If someone wants to provide a patch to make this configurable, however, I might
consider it.
