Subject: ld problem with templates

dear sirs,
I tried to compile a program that uses stl extensivly.
There is no problem to compile it with gnu 2.7.2 under solaris, = linux
and OS/2.
Using gnuwin32 causes hundreds of linker errors like this:
.... multiple definition of = __default_alloc_template<false,0>::...

(all errors occured contain '__default_alloc_template<false,0>::' = !)

Is it a known problem? Should I use other ld options?

options to compile cc files were :
gcc -c xx.cc

options to link the executable were :
gcc -o xx.exe xx.o ... -lstdc++ -lg++ -lm

thanks
S. Triebel
