/*
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.
