What are the location requirements of version.c? Can its path simply be passed to another jam 
target? Things stay cleaner if you create generated files in the build directories instead of your 
source tree.

I recently did some similar stuff with HDF5:

alias H5pubconf.h : src/posix/H5pubconf.h : <include>src/posix : : <include>src/posix ;
alias H5pubconf.h : src/darwin/H5pubconf.h : <toolset>darwin <include>src/darwin : : 
<include>src/darwin ;
alias H5pubconf.h : src/windows/H5pubconf.h : <toolset>msvc <include>src/windows : : 
<include>src/windows ;

project
     : requirements
         <include>src
         <include>c++/src
         <library>/ext/zlib//z
         <library>/ext/boost//thread
         <use>H5pubconf.h
         <warnings>off
     : usage-requirements
         <include>src
         <include>c++/src
         <library>/ext/zlib//z
         <library>/ext/boost//thread
         <use>H5pubconf.h
     ;

exe H5detect : src/H5detect.c ;
actions make_init { "$(>[1]:P)/H5detect" > "$(<)" }
make H5Tinit.c : H5detect : @make_init ;

actions copy_libsettings { cp -f "$(>)" "$(<)" }
make libhdf5.settings : src/posix/libhdf5.settings : @copy_libsettings ;
make libhdf5.settings : src/darwin/libhdf5.settings : @copy_libsettings : <toolset>darwin ;

exe H5make_libsettings : src/H5make_libsettings.c ;
actions make_libsettings
{
     cd $(>[1]:P)
     "$(>[1]:P)/H5make_libsettings" > "$(<)"
}
make H5lib_settings.c : H5make_libsettings libhdf5.settings : @make_libsettings ;
