Reg: -fdump-translation-unit for "C"

[Praveen D V]

hi,
I was earlier using 3.x.x version where I used -fdump-translation-unit to dump
"typedef" tree.   Recently I upgraded to 4.1.x version, unfortunately,
that doesn't
dump the tree any more.  From documentation, it mentions it is for
"C++".  I need it
for "C".
It is a very useful utility.  Are there any other options that replace
-fdump-translation-unit?
--thanks, Praveen
