Overhaul how `build.sh tools' are used: * Rename "config.h" to "nbtool_config.h" and HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H. This makes in more obvious in the source when we're using tools/compat/config.h versus "standard autoconf" config.h * Consistently move the inclusion of nbtool_config.h to before <sys/cdefs.h> so that the former can provide __RCSID() (et al), and there's no need to protect those macros any more. These changes should make it easier to "tool-ify" a program by adding: #if HAVE_NBTOOL_CONFIG_H #include "nbtool_config.h" #endif to the top of the source files (for the general case). 2003-10-27 03:12:41 +03:00			`# $NetBSD: defs.mk.in,v 1.8 2003/10/27 00:12:43 lukem Exp $`
Add the framework for autoconf-based src/tools/compat structure. This will (after it is more fleshed out) allow the host tools to work more cleanly on non-NetBSD hosts. 2001-12-12 00:17:56 +03:00
Make almost all tools compile and run properly on non-NetBSD hosts. (In particular, most tools now run correctly on Solaris 7.) 2002-01-29 13:20:28 +03:00			`COMPATOBJ:= ${.PARSEDIR}`
Make many host tools compile on non-NetBSD hosts. Not complete, but very nearly there. 2002-01-21 23:04:36 +03:00			`HOSTEXEEXT= @EXEEXT@`

Add a HOST_BSHELL make var which contains the path to the working shell. 2002-09-15 20:46:23 +04:00			`HOST_BSHELL= @BSHELL@`

Add a new feature-test macro, _NETBSD_SOURCE. If this is defined by the application, all NetBSD interfaces are made visible, even if some other feature-test macro (like _POSIX_C_SOURCE) is defined. <sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE, _POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve existing behaviour. This has two major advantages: + Programs that require non-POSIX facilities but define _POSIX_C_SOURCE can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS. + It makes most of the #ifs simpler, in that they're all now ORs of the various macros, rather than having checks for (!defined(_ANSI_SOURCE) \|\| !defined(_POSIX_C_SOURCE) \|\| !defined(_XOPEN_SOURCE)) all over the place. I've tried not to change the semantics of the headers in any case where _NETBSD_SOURCE wasn't defined, but there were some places where the current semantics were clearly mad, and retaining them was harder than correcting them. In particular, I've mostly normalised things so that _ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE, _XOPEN_SOURCE and _NETBSD_SOURCE in that order. Tested by building for vax, encouraged by thorpej, and uncontested in tech-userlevel for a week. 2003-04-29 03:16:11 +04:00			`-D_FILE_OFFSET_BITS=64 -D_NETBSD_SOURCE`
