I still have a cygnus-gcc problem which was not present with gnu
gcc-2.7.2.1 . Trying to compile and link 3 C++ modules containing STL
code plus one C-module yields:

Ulrich Drepper already gave me a hint to use the -fno-implicit-templates
option . But then I get lots of "Unsatisfied symbols" messages due to
STL depending on which subset of modules I use this option:

g++ -o simbatst /hpe2/goik/simba/lib/debug/simbatst.a
/hpe2/goik/simba/lib/debug/simbaeng.a simbadrm.a -lm
