Cannot build bjam on Linux with vacpp

[ccambly@…]

If we try to build bjam on linux using xlC the build fails because of an invalid linker option. The file tools/jam/src/build.jam has the following:

## IBM VisualAge C++ toolset vacpp xlc : "-o " : -D

: [ opt --release : -s -O3 -qstrict -qinline ] [ opt --debug : -g -qNOOPTimize -qnoinline -pg ] -I$(--python-include) -I$(--extra-include) : -L$(--python-lib[1]) -l$(--python-lib[2]) -bmaxdata:0x40000000 ;

The -bmaxdata linker option is only valid on AIX. If I am building with xlC on Linux that linker option should not be specified.

The change in the patch file is:

## IBM VisualAge C++ { local linkopt = ; if $(OS) = AIX { linkopt = -bmaxdata:0x40000000 ; } toolset vacpp xlc : "-o " : -D

: [ opt --release : -s -O3 -qstrict -qinline ] [ opt --debug : -g -qNOOPTimize -qnoinline -pg ] -I$(--python-include) -I$(--extra-include) : -L$(--python-lib[1]) -l$(--python-lib[2]) $(linkopt) ;

}

Rene: I couldn't find a uname that worked so I left it as OS
