Hi,

In the meantime I modified both glob.c and regexp.c to correctly handle [a-z] constructs and inserted some additional 
#include's here and there. bjam builds itself correctly.
I also set up a the tool definition - os390xlc.jam in my case - and now I can use my existing Jamfiles to build 
my own projects. This is already a great step forward!

But when I try to build boost libraries bjam only finds one target and does nothing. What do I do wrong? See output 
below.

regards,

Norbert

Building the Boost C++ Libraries.

After the build, the headers will be located at

    /home/u250672/cpp/boost

The libraries will be located at

    /home/u250672/cpp/boost/stage/lib

Use 'bjam install --prefix=<path>' if you wish to 
install headers and

libraries to a different location and remove the source tree.
