State-Changed-Why:
    gcc2.95 is a dead branch. Since it works with 3.0 and later,
    there is no need to keep this report open. If you need to
    make this work on your platform with 2.95, you will have 
    to find a work-around; otherwise try to update your
    compiler.

>How-To-Repeat:
Compile code above. Note this works fine with g++ 3.0 and higher, but not with 2.95.4. I got this error message:

g++    -c -o main.o main.cc
main.cc: In method `void myclass1<dum>::test()':
main.cc:20:   instantiated from here
main.cc:11: `volatile' undeclared (first use this function)
main.cc:11: (Each undeclared identifier is reported only once
main.cc:11: for each function it appears in.)
main.cc:11: warning:  qualifier ignored on asm
make: *** [main.o] Error 1
