* Use LITTLE_ENDIAN instead of __LITTLE_ENDIAN (LITTLE_ENDIAN is what POSIX now specifies and everyone seems to define - NetBSD also defines _LITTLE_ENDIAN, but not __LITTLE_ENDIAN) * file descriptors greater than 2 must be explicitly passed to a child on NetBSD. POSIX leaves that unspecified, see https://pubs.opengroup.org/onlinepubs/9799919799/utilities/V3_chap02.html#exec * system library functions get declared with visibility "default" on NetBSD, so a "hidden" visibility attribute is ignored on a redeclaration. Work around by putting the functions in a namespace - as they are extern "C", they still end up in the object file without the namespace qualifier. * remove the cast on the NULL pointer on the funopen call - it's not needed and the types are different between FreeBSD (fpos_t) and NetBSD/OpenBSD (off_t); also trying to change that upstream https://github.com/openSUSE/libsolv/pull/603 Change-Id: I6ab7f3c74d18960d7589b403a1c219cdac85a453 Reviewed-on: https://review.haiku-os.org/c/haiku/+/10133 Tested-by: Commit checker robot <[email protected]> Reviewed-by: Adrien Destugues <[email protected]>
