Thanks for your bug report. It sure is platform-dependent.

Please have a look at http://gcc.gnu.org/cgi-bin/fom.cgi?file=25

Well, it is a fatal error. It is ill-formed C++. It was deprecated in
C, hence the warning. It was ill-formed in C++ all the time, and g++
should have never been that permissive with it - it only led to Sun
not fixing their headers. It even is ill-formed in C today.

That is primarily a problem of the header files, and not of
g++. Please complain to Sun.

Did you try your fix? /usr/openwin/include is not a system header...
