Hi,
finally I discovered the problem : it was a fault in my makefile.
I wrote this makefile after I read a tutorial on make on an italian
Linux magazine; then I joined it with the previous makefile I used (from early
2.95 avr-gcc distribution).
Merging together the tutorial and the old makefile, the line

#EXT = cpp
EXT = c

%o: %$(EXT)
 $(CC) -c $(CFLAGS) $< -o $@

was missed.

With C source files, all is ok even if this line is missed.
When I changed the source extension from .c to .cpp (or .cc), make was
not able to compile; after some tries, I changed the compiler called
in the makefile from avr-gcc to avr-g++ leaving the source file
extension .c and writing in C++. The compiler did all ok, but gdb
considered C source files and not C++ files.
I have added the line missed, and now AVR-Insight shows the function names as
class::function.

I have attached the makefile I use : it is not commented, but changing
the LANGUAGE definition, can compile C and C++ projects with WinAVR.
Also, make find automatically the source files of the current directory.
