This patch enables wchar support on FreeBSD 5 and disables it on older versions.
Unfortunately, I can't remember, why BOOST_NO_INCLASS_MEMBER_INITIALIZATION was necessary, but it won't hurt, will it?
Probably not, but it still looks like a mistake: gcc-3.3 shouldn't have any issues with this.

Simplified to just: #if !(defined(__FreeBSD__) && (__FreeBSD__ >= 5)) # define BOOST_NO_CWCHAR #endif Tested on FreeBSD 5 via HP testdrive, and looks OK.
Depending on the FreeBSD version, different compiler and linker options are needed. These option are provided by two environment variables PTHREAD_CFLAGS and PTHREAD_LIBS, but I found no other way of getting the right values into Boost's config files than patching that will placeholder values and using sed(1) to replace those dummies with the actual ones.
You can use $(NAME) to refer to an environment variable in bjam, so I assume that this should be:
case *BSD : { - flags gcc LINKFLAGS <stlport-iostream>on : -pthread ; + flags gcc LINKFLAGS <stlport-iostream>on : $(PTHREAD_LIBS) ; }
But maybe a bjam expert can comment.
The first hunk of the patch is needed because ports in FreeBSD are supposed to obey some global CFLAGS settings (whose optimiziation settings would be overridden by -O0).
The second hunk is similar to the last patch.
Again this can refer to the environment variables directly I believe.
This patch is needed for FreeBSD 4 (gcc 2.95) only!
I am sure the first hunk could be solved more cleanly by some configuration option, but where?
The second hunk is something I am really unsure about, and which I suppose has something to do with FreeBSD's (or gcc 2.95's?) implementation of std::codecvt. Is this necessary on other platforms?
It looks like a bug in the program_options code to me, there probably shouldn't be a using ::codecvt; there at all. John.
