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 <errno.h> header defines the numbers of the various errors that can
|
|
* occur during program execution. They are visible to user programs and
|
|
* should be small positive integers. However, they are also used within
|
|
* MINIX, where they must be negative. For example, the READ system call is
|
|
* executed internally by calling do_read(). This function returns either a
|
|
* (negative) error number or a (positive) number of bytes actually read.
|
|
*
|
|
* To solve the problem of having the error numbers be negative inside the
|
|
* the system and positive outside, the following mechanism is used. All the
|
|
* definitions are are the form:
|
|
*
|
|
* <define> EPERM (_SIGN 1 )
|
|
*
|
|
* If the macro _SYSTEM is defined, then _SIGN is set to "-", otherwise it is
|
|
* set to "". Thus when compiling the operating system, the macro _SYSTEM
|
|
* will be defined, setting EPERM to (- 1), whereas when when this
|
|
* file is included in an ordinary user program, EPERM has the value ( 1).
