From: Eric Andersen Date: Mon, 3 Nov 2003 21:20:18 +0000 (-0000) Subject: Fix rdate and ftpget/ftpput so they compile with the new xconnect. X-Git-Tag: 1_00_pre4~84 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=04d055f4e11469f74bdde38837deefab27edb2e9;p=oweals%2Fbusybox.git Fix rdate and ftpget/ftpput so they compile with the new xconnect. I have checked rdate. Someone should also check ftpget/ftpput to be sure they still work. --- diff --git a/include/libbb.h b/include/libbb.h index 53062de4d..945dc95bc 100644 --- a/include/libbb.h +++ b/include/libbb.h @@ -295,8 +295,8 @@ extern struct hostent *xgethostbyname2(const char *name, int af);
