Simon: I was able to compile the latest patch revision of 3.5.2 in C++03 mode on GCC and MSVC without modifying the src.
All: ... but Solaris Studio and the AIX XL compiler are no bueno because of some template metaprogramming constructs which may or may not be part of the C++03 spec itself. I didn't save the errors because I tried both 3 months ago and gave up trying to work around the errors, as too many classes in a couple of headers had the same error (part of the error was template specialization IIRC). I suspect I'm the only one here who has any interest in compiling on XL and Solaris Studio (needed to link with other libs built using the same compiler), but if not I can try again and attach compilation error output.
