It would seem so.  You can use "gccxml -E" to preprocess the test
source and compare it to what "gcc -E" produces for the offending
spot.  Note that gccxml uses a patched GCC 4.2 parser internally
so sometimes it has trouble with headers from newer GCC versions.
The solution we use is to put tweaked versions of the offending
headers in "GCC_XML/Support/GCC/4.4" or other support directories.
You can copy the header to that location in gccxml and then modify
it to correct the error.  If you get it working please send me the
patch and I'll include it upstream.

Thanks,
