+   Get rid of the path to talon from a commandline string on windows find the 
+   -c (if it's there) and step past it to after the quote on the first command:
+
+   "g:\program files\talon\talon.exe" -c "gcc -c . . ."
+                                          ^------ Returns a pointer to here
+
+   Take care of the possibilty that there might be spaces in the command
+   if it is quoted.
+
+   A state-machine is flexible but not all that easy to write.  Should investigate
+   the possiblity of using the Ragel state machine generator perhaps.
