hppa2.0w-hp-hpux11.00 linker error: spurious behaviour of -fweak (differs from i686-pc-linux-gnu)

Hi!

I finally found out what gave me linkage errors on hpux:

option -fweak hinders template instatiation on hpux  every second time
Look at this

[markus]  HP_LINKER_BUG/ > rm *.o

[markus]  HP_LINKER_BUG/ > make
g++ -fweak -c Test.C
g++ -fweak -c main.C
g++ -fweak  -o test.exe Test.o main.o
collect: recompiling Test.C
collect: relinking
/usr/ccs/bin/ld: Unsatisfied symbols:
   Test<Dummy>::DoIt()     (code)
collect2: ld returned 1 exit status
make: *** [all] Error 1

[markus]  HP_LINKER_BUG/ > rm *.o

[markus]  HP_LINKER_BUG/ > make
g++ -fweak -c Test.C
g++ -fweak -c main.C
g++ -fweak  -o test.exe Test.o main.o
collect: recompiling Test.C
collect: relinking

AND SO ON, reproducable!
Any explanation?
