2014-09-10	add _DEFAULT_SOURCE feature profile as an alias for _BSD_SOURCE	Rich Felker	-0/+4
	as a result of commit ab8f6a6e42ff893041f7545a23e6d6a0edde07fb, this definition is now equivalent to the actual "default profile" which appears immediately below in features.h, and which defines both _BSD_SOURCE and _XOPEN_SOURCE. the intent of providing a _DEFAULT_SOURCE, which glibc also now provides, is to give applications a way to "get back" the default feature profile when it was lost either by compiler flags that inhibit it (such as -std=c99) or by library-provided predefined macros (such as -D_POSIX_C_SOURCE=200809L) which may inhibit exposure of features that were otherwise visible by default and which the application may need. without _DEFAULT_SOURCE, the application had encode knowledge of a particular libc's defaults, and such knowledge was fragile and subject to bitrot. eventually the names _GNU_SOURCE and _BSD_SOURCE should be phased out in favor of the more-descriptive and more-accurate _ALL_SOURCE and _DEFAULT_SOURCE, leaving the old names as aliases but using the new ones internally. however this is a more invasive change that would require extensive regression testing, so it is deferred.
2014-09-10	fix _ALL_SOURCE logic to avoid possible redefinition of _GNU_SOURCE	Rich Felker	-1/+1
	this could be an error if _GNU_SOURCE was already defined differently by the application.
2012-12-03	add _ALL_SOURCE as an alias for _GNU_SOURCE/enable-everything	Rich Felker	-0/+4
	reportedly this is a semi-common practice among some BSDs and a few other systems, and will improve application compatibility.
2012-09-07	default features: make musl usable without feature test macros	Rich Felker	-1/+28
	the old behavior of exposing nothing except plain ISO C can be obtained by defining __STRICT_ANSI__ or using a compiler option (such as -std=c99) that predefines it. the new default featureset is POSIX with XSI plus _BSD_SOURCE. any explicit feature test macros will inhibit the default. installation docs have also been updated to reflect this change.
