First of all, it's not polite to send things twice just because nobody 
answered you.

Second, people on this listcould have as well ignored you because this 
is a mailing list for development "of" GCC, not "with" GCC.  There's 
another list for the latter purpose, which is gcc-help@gcc.gnu.org.  To 
be clearer, a proper message to this list would be "I would like to 
write a unified front-end for C and C++, in order to be able to look at 
the .tu dump which right now I can only use with the C++ front-end.  Do 
you have estimates of the effort needed?" or "I would like to add .tu 
dumps to the C front-end.  Do you have estimates of the effort needed?" 
  And even then, an answer would not be guaranteed.

Third, the answer to your question is that the only solution is to write 
your code in the intersection of C and C++, which I agree can be hard if 
you do not control the code you're running the tool on.  -fpermissive 
can ease things, but it is not of course a silver bullet.
