 I am using gccxml, built from current cvs at
   www.gccxml.org:/cvsroot/GCC_XML
 On Windows XP SP3, with Visual Studio version 9.0.30729.1 SP (SP1)

 // file test.hpp:
 {{{
 #include <boost/typeof/typeof.hpp>
 }}}

 typing this command:


 {{{
    gccxml -I"C:/Program Files/boost/boost_1_43_0" test.hpp
 }}}


 yields the following error message:

 ##################

 {{{
 In file included from C:/Program
 Files/boost/boost_1_43_0/boost/typeof/typeof.hpp:103,
                  from test3.hpp:1:
 C:/Program Files/boost/boost_1_43_0/boost/typeof/msvc/typeof_impl.hpp:151:
 error: qualified name does not name a class before '{' token
 }}}

 ##################

 The code in question appears on a block of the form


 {{{
 #if BOOST_WORKAROUND(BOOST_MSVC,==1300)
 // Code specific to VC 7.0.
 #elif BOOST_WORKAROUND(BOOST_MSVC,>=1400)
 // Code for VC 8.0 and above.
 #else
 // Code commented with "This uses nice VC6.5 and VC7.1 bugfeature"
 // that does not work with gccxml.  Error is reported here.
 #endif
 }}}


 I'd guess it should be choosing the middle block here.  My fumbling
 attempts at preprocessor debugging suggest that the "BOOST_MSVC" macro is
 undefined when gccxml is emulating msvc here.

 The gccxml preprocessor simulates the definitions
 of the target compiler, but adds __GCCXML__ to distinguish
 itself.

 Sorry I don't have a patch to submit.  I'm unsure what the right way to
 handle this is.
