Hello, I'm not sure wether this has been already discussed. wave library in Boost 1-33-1 distribution fails to compile with msvc 7.1 sp1 (compiler version 13.10.6030) with the following error: vc-C++ bin\boost\libs\wave\build\libboost_wave.lib\vc-7_1\debug\rtti-off\runtime-link-static\instantiate_cpp_grammar.obj instantiate_cpp_grammar.cpp c:\boost_1_33_1\boost\spirit\core\composite\alternative.hpp(60) : fatal error C1002: compiler is out of heap space in pass 2 "cl" /Zm800 -nologo /EHsc -c /Z7 /Od /Ob0 /EHsc /MLd /Op /wd4675 /Zc:forScope /Zc:wchar_t -I"bin\boost\libs\wave\build" -I"C:\boost_1_33_1" -I"C:\Program Files\Microsoft VisualStudio .NET 2003\VC7\include" -I"C:\boost_1_33_1" -Fo"bin\boost\libs\wave\build\libboost_wave.lib\vc-7_1\debug\rtti-off\runtime-link-static\instantiate_cpp_grammar.obj" -Tp"C:\boost_1_33_1\libs\wave\build\../src/instantiate_cpp_grammar.cpp" ...failed vc-C++ bin\boost\libs\wave\build\libboost_wave.lib\vc-7_1\debug\rtti-off\runtime-link-static\instantiate_cpp_grammar.obj...
