[antlr-interest] C++ file timestamps and makefiles

[Bryan Ewbank]

I've noticed some strange behavior, and need confirmation.  It appears
that ANTRL only creates C++ output files if the output file is
different than the previously generated file.

For example, unless I add a new token, the *TokenTypes* files are not
updated.  If I change the action associated with a rule, only the
*.cpp file is changed - the *.hpp is unchanged.

Is this expected of ANTLR, or do I need to be looking elsewhere to
figure out what is going on?

Thanks
