Hi !

I'm back from vacation and got M4 (current CVS) running again.
I've encountered several problems with it.

1. Vladimir added correct handling of .c extension. Unfortunately, I 
have an external lib which is C++m, but whose extension is .c 
Is there an easy way to get bjam to use always g++ ?
If not, I'm just happy to use the original Makefiles and link against 
the resulting lib.

2. Platform dependent dependencies.
I'm now working on a different project which imports and later exports 
tiff Images using libtiff. Developing on Linux/Windows. So I've got to 
link against differrent libs on different platforms.

I tried something along

lib tiff : : <os>LINUX <name>tiff ;
lib tiff : : <os>NT <name>$(TIFF_ROOT)/libtiff/tiff.lib ;

but now linux os.jam chokes on unknown feature NT and vice versa.
Is there any chance to get this working in M5 ? Or am I using the wrong 
mechanism ? It would be great if the examples/docs would contain code 
covering this. 

3. STLport.

Working great, but find a diff attached which eliminates annoying

warning: target id '@/stlport/stlport uses deprecated syntax,
warning: which may be removed in a future version.
warning: reference is made from project at 'RailSys/simu'

I wonder if bjam could support static linking of STLport on Win32 using

<define>_STLP_USE_STATIC_LIB
<define>_RTLDLL

somehow.
This results in linking against static lib, using system runtime.
It uses special stlport lib with _staticx extension, build by stlport 
make target "staticx". It is quite useful, because I dont have to 
deliver STLport .dll to my customers. 

4. Qt-Toolset
I'm trying to add support for qt-uic "embedding" feature.
This is used by Qt-Designer to embed *.png files in a C++ source code.
The files are compiled with the command line
uic -embed <unique id> <list-of .png files> - o embedded.cpp 

Thomas Witt and I have hacked some code for V1.
Can someone drop me a hint how I can start to implement this on V2.
And I thought I could add some more user friendliness on Win32 (library 
name, defines etc.) 

5. Speed
I read this is coming with M6 along with test system.
This wil be cool.

Keep up the good work !

Yours,

Jürgen
