There is important information about booting non-ack images in docs/UPDATING. ack/aout-format images can't be built any more, and booting clang/ELF-format ones is a little different. Updating to the new boot monitor is recommended. Changes in this commit: . drop boot monitor -> allowing dropping ack support . facility to copy ELF boot files to /boot so that old boot monitor can still boot fairly easily, see UPDATING . no more ack-format libraries -> single-case libraries . some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases . drop several ack toolchain commands, but not all support commands (e.g. aal is gone but acksize is not yet). . a few libc files moved to netbsd libc dir . new /bin/date as minix date used code in libc/ . test compile fix . harmonize includes . /usr/lib is no longer special: without ack, /usr/lib plays no kind of special bootstrapping role any more and bootstrapping is done exclusively through packages, so releases depend even less on the state of the machine making them now. . rename nbsd_lib* to lib* . reduce mtree

/* The <minix/ansi.h> header attempts to decide whether the compiler has enough
|
|
* conformance to Standard C for Minix to take advantage of. If so, the
|
|
* symbol _ANSI is defined (as 31459). Otherwise _ANSI is not defined
|
|
* here, but it may be defined by applications that want to bend the rules.
|
|
* The magic number in the definition is to inhibit unnecessary bending
|
|
* of the rules. (For consistency with the new '#ifdef _ANSI" tests in
|
|
* the headers, _ANSI should really be defined as nothing, but that would
|
|
* break many library routines that use "#if _ANSI".)
|
|
|
|
* If _ANSI ends up being defined, a macro
|
|
*
|
|
* _PROTOTYPE(function, params)
|
|
*
|
|
* is defined. This macro expands in different ways, generating either
|
|
* ANSI Standard C prototypes or old-style K&R (Kernighan & Ritchie)
|
|
* prototypes, as needed. Finally, some programs use _CONST, _VOIDSTAR etc
|
|
* in such a way that they are portable over both ANSI and K&R compilers.
|
|
* The appropriate macros are defined here.
