preprocessed source

The enclosed ought to compile, but instead I get:

c:/boost/boost/iterator/transform_iterator.hpp: In instantiation of 
   `boost::transform_iterator<int (*)(int), int *, boost::use_default,
boost::use_default>':
c:/boost/boost/iterator/transform_iterator.hpp:127: no type named `type' in 
   `boost::detail::enable_if<boost::mpl::not_<boost::is_pointer<int (*)(int)>
>, char>'

Note that there's no instantiation backtrace!  Very strange.

Compile command:
    g++  -fmessage-length=0  -c -Wall -ftemplate-depth-100   -g -O0 -fno-inline
   -I "c:\boost"  -o
"bin\transform_iterator_test.test\gcc\debug\runtime-link-dynamic\transform_iterator_test.obj"
 "transform_iterator_test.cpp"
