Perl? Well you need a time machine just to reach the present... :) Anyway, that setup sounds too complex...Perl generated macros further expanded by the preprocessor... A bug in that tool path can be the most hard to detect...
Good luck!!!
It's been 2 decades since I last programmed in C. But all I remember of Macros is that some of the most difficult bugs to spot in C code lives in Macros. A missing paranthesis, unthoughtful coding can make it extremely difficult to spot the bug.
Also makes code unreadable...Check out Linux source...
