From 4b8333decafe6c9495555aaecae4c392bdae1874 Mon Sep 17 00:00:00 2001 From: Fred Fish Date: Sun, 1 Mar 1992 21:20:04 +0000 Subject: [PATCH] xm-sysv4.h: Provide definitions/prototypes for host environment functions for which no definitions or prototypes are provided in any currently included gdb or host environment header files. For SVR4, this currently includes malloc and realloc, which cannot be portably prototyped in any gdb include file. --- gdb/ChangeLog | 52 ++++++++++++++++++++++++++++++++++++++++++++++++++ gdb/xm-sysv4.h | 15 +++++++++++++++ 2 files changed, 67 insertions(+) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 821d3c029a0..20ea9bbfa37 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,55 @@ +Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com) + + * xm-sysv4.h: Provide definitions/prototypes for host environment + functions for which no definitions or prototypes are provided in + any currently included gdb or host environment header files. + For SVR4, this currently includes malloc and realloc, which cannot + be portably prototyped in any gdb include file. + +Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com) + + * buildsym.h: Remove obsolete variable file_stabs. + + * Makefile.in: Move place where configure merges in host- + and target-dependent fragments later, so the latter + can override (say) GNU_MALLOC. + * config/mh-rs6000: Use system malloc.
