Here's a test-case for you. Save the attached source file as
/tmp/test.cpp and run the following g++ invocation:
g++ -c -g -O0 -fno-strict-aliasing -Wall -W -Wno-format-y2k \
-Wpointer-arith -Wwrite-strings -o /tmp/test.o /tmp/test.cpp
When I run this command against the attached file I get:
/tmp/test.cpp: In function ‘int do_test()’:
/tmp/test.cpp:14: warning: deprecated conversion from string constant to ‘char*’'
But if you look the argument IS a const, just through a typedef.
I'm using g++ 4.1.1-1 on FC5:
