From 61c83c3f0573d03cda87717ee46b5c985c4646fd Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sun, 17 Feb 2002 07:19:11 +0000 Subject: * sysdeps/mach/configure.in: Add some checks for Mach headers to ensure a sane installation. (mach_interface_list): Define this variable by checking for .defs files found in various variants. * configure.in (mach_interface_list): AC_SUBST this. * config.make.in (mach-interface-list): New substituted variable. * mach/Makefile (user-interfaces): Define this using the value of $(mach-interface-list) instead of mach, mach4. Updated other references to mach_interface to use it as well. * sysdeps/mach/powerpc/machine-lock.h: Avoid multi-line strings. * mach/msgserver.c [NDR_CHAR_ASCII] (mig_reply_header_t): #define as mig_reply_error_t for OSF Mach variant. * mach/Makefile (routines): Remove bootprivport. * mach/bootprivport.c: File removed. It has never been used. * mach/msg-destroy.c (__mach_msg_destroy) [MACH_MSG_PORT_DESCRIPTOR]: Grok the OSF flavor of message format. (mach_msg_destroy_port): For MAKE_SEND and MAKE_SEND_ONCE rights, create an destroy a right to ensure proper no-senders notification. 2002-02-06 Roland McGrath * hurd/Versions (libc: GLIBC_2.0): Move cthread_fork, cthread_detach to here if 2.0 compatibility enabled ... (libc: GLIBC_2.1.3): ... from here. --- sysdeps/mach/configure.in | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) (limited to 'sysdeps/mach/configure.in') diff --git a/sysdeps/mach/configure.in b/sysdeps/mach/configure.in index 2a76ead8ed..058a2a05c8 100644 --- a/sysdeps/mach/configure.in +++ b/sysdeps/mach/configure.in @@ -1,6 +1,11 @@ sinclude(./aclocal.m4)dnl Autoconf lossage.
