Subject: linux-user/syscall.c: remove wrong forward decl of setgroups()
X-Git-Tag: v1.4.0-rc0~281^2~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c56dc774242f902e51e2343f4472e742ef2b7838;p=thirdparty%2Fqemu.git

linux-user/syscall.c: remove wrong forward decl of setgroups()

this declaration is wrong:
the correct prototype on linux is:
int setgroups(size_t size, const gid_t *list);

since by default musl libc exposes this symbol in unistd.h
additionally to grp.h, the wrong declaration causes a build error.

the proper fix is to simply include the correct header.
