797229 - Fix two warnings in updater.cpp

Status: RESOLVED FIXED

(Toolkit :: Application Update, defect)

Description

[:ehsan akhgari]

toolkit/mozapps/update/updater/updater.cpp:2035:1 [-Wunused-function] unused function 'ReadMARChannelIDs'
toolkit/mozapps/update/updater/updater.cpp:2132:14 [-Wdeprecated-writable-strings] conversion from string literal to 'char *' is deprecated

The first one is easy.  The second one is technically a bug, since putenv() accepts a char*, not a const char*.

Hrm, is it implementation specific or is one of these 2 documentation pages wrong?
http://www.bigbiz.com/cgi-bin/manpage?3+putenv
http://linux.die.net/man/3/putenv
MSDN also lists it as a const char* btw.

Unix defines it as char* <http://pubs.opengroup.org/onlinepubs/009604599/functions/putenv.html>, and both on my Mac and Ubuntu box, it's char*.
