* main.c: <stdlib.h> is needed, to introduce the getenv(3)
prototype declaration. Without it a C compiler shall infer the getenv type as "int getenv(...);", but this is totally wrong, especially when your machine's sizeof(int) and sizeof(char*) differs. On such environment a return value of getenv(3), which is in fact a char*, might first casted into a int (loses data here), and then casted back to char* by automatic integral promotion fo fit to the prototype of ruby_set_debug_option(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@29658 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
