anyone else out there playing along?

try this patch on for size. regenerate. watch it bail. but a bit
closer.

it puts -I($top_srcdir)/shadow before -I($top_srcdir) so the
bits/* includes to define _IN_C_LEGACY_ are found

======================

... still having a namespace problem though. hardcoding 'using 
namespace _C_legacy' lets it compile, but I'll look more for the real 
solution after I read Nathan's site a bit more -- likely tomorrow 
evening. error is below. the __convert_long_double_i _is_ defined
in the intermediate file (g++ -E...), just not visible.
