Excuse for my inaccurasy in the previous E-mail. Anyway i have obtained
from compiler the following log:
--------------------Configuration: prova2 - Debug--------------------
Compiling...
prova8.cpp
D:\Documenti\prova2\prova8.cpp: In function `void my_fun2() [with T = float]':
D:\Documenti\prova2\prova8.cpp:9: instantiated from `void my_fun1() [with
T = float]'
D:\Documenti\prova2\prova8.cpp:19: instantiated from here
D:\Documenti\prova2\prova8.cpp:14: warning: unused variable `float prova'
prova8.o - 2 error(s), 1 warning(s)

the code above should be correct (and compiles with g++).
(BTW: Please don't say "there is an error ...", but give **details**!!
Just copy the error message.
And perhaps better send your mail (also) to the list so that other people
can participate and/or learn from it.)
