If the source code #includes y.tab.h, then it must already be the case
that there is only one .y file used by that code. If that were not
true, then the code is already broken: How does it know which y.tab.h
it will get? So no renaming should be necessary in this case.
Perhaps you could define a YRENAME variable which would determine
whether the output files are renamed or not.
Which utilities in the tree use multiple .l or .y files, anyway?
