default features: make musl usable without feature test macros 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. 2012-09-08 03:13:55 +00:00			`#include <features.h>`

make brace placement in public header struct definitions consistent placing the opening brace on the same line as the struct keyword/tag is the style I prefer and seems to be the prevailing practice in more recent additions. these changes were generated by the command: find include/ arch//bits -name '.h' \ -exec sed -i '/^struct [^;{]*$/{N;s/\n/ /;}' {} + and subsequently checked by hand to ensure that the regex did not pick up any false positives. 2016-07-03 18:40:11 +00:00			`struct FTW {`

remove LFS64 programming interfaces (macro-only) from _GNU_SOURCE these badly pollute the namespace with macros whenever _GNU_SOURCE is defined, which is always the case with g++, and especially tends to interfere with C++ constructs. as our implementation of these was macro-only, their removal cannot affect any existing binaries. at the source level, portable software should be prepared for them not to exist. for now, they are left in place with explicit _LARGEFILE64_SOURCE. this provides an easy temporary path for integrators/distributions to get packages building again right away if they break while working on a proper, upstreamable fix. the intent is that this be a very short-term measure and that the macros be removed entirely in the next release cycle. 2022-09-27 19:04:05 +00:00			`#if defined(_LARGEFILE64_SOURCE)`
add support for ugly *64 functions with _LARGEFILE64_SOURCE musl does not support legacy 32-bit-off_t whatsoever. off_t is always 64 bit, and correct programs that use off_t and the standard functions will just work out of the box. (on glibc, they would require -D_FILE_OFFSET_BITS=64 to work.) however, some programs instead define _LARGEFILE64_SOURCE and use alternate versions of all the standard types and functions with "64" appended to their names. we do not want code to actually get linked against these functions (it's ugly and inconsistent), so macros are used instead of prototypes with weak aliases in the library itself. eventually the weak aliases may be added at the library level for the sake of using code that was originally built against glibc, but the macros will still be the desired solution in the headers. 2012-05-04 04:13:23 +00:00			`#define ftw64 ftw`
