Unless __STRICT_ANSI__ is defined (as it is when running the compiler in --std=c89 or --std=c99, but not when running it without any specific args), we can enable these by default and behave like most other systems. I don't know why no one has done this yet despite suggesting it multiple times and people prefer to #define _BSD_SOURCE manually everywhere. Remove all places in our Jamfiles and sources where it had been defined. _DEFAULT_SOURCE is now enabled by default for all sources of Haiku, since we let the compiler use GNU extensions (no strict C standard specified on command line) Use _DEFAULT_SOURCE as the define name to match current versions of glibc. Enable it if _BSD_SOURCE is #defined in compiler flags, for backward compatibility.
