Public bug reported:
Description: Ubuntu 12.04 LTS
Release: 12.04
nana:
Installed: 2.5-12
Candidate: 2.5-12
Version table:
*** 2.5-12 0

This test file:
--- BEGIN ---
#include "eiffel.h"
int main(int argc, char** argv)
{
ENSURE(true);
return 0;
}
--- END ---
when compiled with gcc 4.6.3: `g++ -Wall nana_test.cc`, gets the
following warnings:
nana_test.cc: In function ‘int main(int, char**)’:
nana_test.cc:5:3: warning: deprecated conversion from string constant to
‘char*’ [-Wwrite-strings]
nana_test.cc:5:3: warning: deprecated conversion from string constant to
‘char*’ [-Wwrite-strings]
nana_test.cc:5:3: warning: deprecated conversion from string constant to
‘char*’ [-Wwrite-strings]
nana_test.cc:5:3: warning: deprecated conversion from string constant to
‘char*’ [-Wwrite-strings]
I expect to be able to use ENSURE and related nana macros with -Wall and
not get compiler warnings.
These warnings are caused by this declaration in I.h:
void _I_default_handler(char *expr, char *file, int line);
Both expr and file should be of type "const char*". The attached patch
fixes the problem by adding a const to both parameters in I.h and I.c.
