|Title||MPS produces warnings when compiled with -Wwrite-strings|
|Assigned user||Gareth Rees|
|Description||When compiled with clang -Wwrite-strings, the MPS fails to compile:|
arenavm.c:1788:14: error: assigning to 'char *' from 'const char ' discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers]
this->name = "VM";
This problem came up when trying to integrate the MPS with Ruby, which compiles with -Wwrite-strings. In order to make integrations go smoothly, the MPS ought to compile under the most stringent compiler options like this.
|Analysis||There are going to be quite a lot of "char *" to "const char *" changes.|
|Evidence||None as yet.|

* Use const char * in places where we want to assign string constants.
Avoid warnings when compiling with -Wextra:
* Avoid if statement with empty body in amcsshe.c
* Avoid comparison of unsigned >= 0.

Add missing initializer to mps_args_none.
Change "char *" to "const char *" where necessary.
