Comment(by jan.boehme@…):

 Hi Volodya!

 Sorry for missing something. A rule like this is given:

 lib mixture : source.f csource.cpp ;
 {{{
 bjam -a -d2 mixture link=shared
 }}}
 leads to the following output:

 {{{
 gcc.compile.fortran bin/gcc-4.4.3/debug/source.o

   "g++"  -O0 -fno-inline -Wall -g     -c -o "bin/gcc-4.4.3/debug/source.o"
 "source.f"

 gcc.compile.c++ bin/gcc-4.4.3/debug/csource.o

     "g++"  -ftemplate-depth-128 -O0 -fno-inline -Wall -g -fPIC     -c -o
 "bin/gcc-4.4.3/debug/csource.o" "csource.cpp"

 gcc.link.dll bin/gcc-4.4.3/debug/libmixture.so
 }}}

 As you can see, only the cpp-object was compiled using "-fPIC".

 With "implicit" I want to say that the gnu fortran compiler will be used
 implicitly here. What if I want to use gnu for C++ only and the intel
 tools for fortran? I guess I would get errors caused by ambiguous
 generators.

 Cheers, Jan.
