Bug #43414 Parenthesis (and other) warnings compiling MySQL
with gcc 4.3.2 This patch fixes a number of GCC warnings about variables used before initialized. A new macro UNINIT_VAR() is introduced for use in the variable declaration, and LINT_INIT() usage will be gradually deprecated. (A workaround is used for g++, pending a patch for a g++ bug.) GCC warnings for unused results (attribute warn_unused_result) for a number of system calls (present at least in later Ubuntus, where the usual void cast trick doesn't work) are also fixed. client/mysqlmanager-pwgen.c: A fix for warn_unused_result, adding fallback to use of srand()/rand() if /dev/random cannot be used. Also actually adds calls to rand() in the second branch so that it actually creates a random password.
