This now makes ksh build on DragonFly BSD. bin/package, src/cmd/INIT/package.sh: - DragonFly also needs the -lm hack for LDFLAGS. src/cmd/ksh93/sh/main.c, src/cmd/ksh93/tests/basic.sh: - fixargs() doesn't work on DragonFly either (re:9b7c392a,159fb9ee,cefe087d). The following are backported from: https://github.com/att/ast/issues/26#issuecomment-313927854 https://github.com/att/ast/pull/19 src/lib/libast/comp/setlocale.c: - Add missing #include <errno.h> since errno is used. src/lib/libast/features/standards: - Do not set any standards macros (_POSIX_SOURCE etc) on FreeBSD or DragonflyBSD; they disable too much functionality on those. src/lib/libast/features/wchar: - Set _STDFILE_DECLARED on DragonFly, too. src/lib/libast/include/sfio.h, src/lib/libast/include/sfio_t.h, src/lib/libast/sfio/_sfopen.c, src/lib/libast/sfio/sfclrlock.c, src/lib/libast/sfio/sfhdr.h, src/lib/libast/sfio/sfnew.c, src/lib/libast/sfio/sfset.c: - Rename SF_* macros to SFIO_* to avoid a conflict with system headers. src/lib/libast/string/strexpr.c: - Rename error() to err() to avoid a conflict.
