via INCS. Implemented INCSLINKS (equivalent to SYMLINKS) to
handle symlinking include files. Allow for multiple groups of
include files to be installed, with the powerful INCSGROUPS knob.
Documentation to follow.
Added standard `includes' and `incsinstall' targets, use them
in Makefile.inc1. Headers from the following makefiles were
not installed before (during `includes' in Makefile.inc1):
kerberos5/lib/libtelnet/Makefile
lib/libbz2/Makefile
lib/libdevinfo/Makefile
lib/libform/Makefile
lib/libisc/Makefile
lib/libmenu/Makefile
lib/libmilter/Makefile
lib/libpanel/Makefile
Replaced all `beforeinstall' targets for installing includes
with the INCS stuff.
Renamed INCDIR to INCSDIR, for consistency with FILES and SCRIPTS,
and for compatibility with NetBSD. Similarly for INCOWN, INCGRP,
and INCMODE.
Consistently use INCLUDEDIR instead of /usr/include.
gnu/lib/libstdc++/Makefile and gnu/lib/libsupc++/Makefile changes
were only lightly tested due to the missing contrib/libstdc++-v3.
I fully tested the pre-WIP_GCC31 version of this patch with the
contrib/libstdc++.295 stuff.
These changes have been tested on i386 with the -DNO_WERROR "make
world" and "make release".
modules split across several physical medias. Following is how it works:
The splitfs code, when asked to open "foo" looks for a file "foo.split"
which is a text file containing a list of filenames and media names, e.g.
foo.aa "Kernel floppy 1"
foo.ab "Kernel floppy 2"
foo.ac "Kernel and modules floppy"
For each file segment, the process is:
- try to open the file
- prompt "Insert the disk labelled <whatever> and press any key..."
- try to open the file
- return error if file could not be located
RE team is free to use this feature in the upcoming 5.0-DP1.

device drivers for bus system with other endinesses than the CPU (using
interfaces compatible to NetBSD):
- bwap16() and bswap32(). These have optimized implementations on some
architectures; for those that don't, there exist generic implementations.
- macros to convert from a certain byte order to host byte order and vice
versa, using a naming scheme like le16toh(), htole16().
These are implemented using the bswap functions.
- stream bus space access functions, which do not perform a byte order
conversion (while the normal access functions would if the bus endianess
differs from the CPU endianess).
htons(), htonl(), ntohs() and ntohl() are implemented using the new
functions above for kernel usage. None of the above interfaces is currently
exported to user land.
Make use of the new functions in a few places where local implementations
of the same functionality existed.

kernels. The error message was "elf_loadexec: cannot seek".
Libstand maintains a read-ahead buffer for each open file, so that
it can read in chunks of 512 bytes for greater efficiency. When
the loader tries to lseek forward in a file by a small amount, it
sometimes happens that the target file offset is already in the
read-ahead buffer. But the lseek code simply discarded the contents
of that buffer and performed a seek directly on the underlying
file. This resulted in an attempt to seek backwards in the file,
since some of the data has already been read into the read-ahead
buffer. Gzipped data streams cannot seek backwards, so an error
was returned.
This commit adds code which checks to see if the desired file offset
is already in the read-ahead buffer. If it is, the code simply
adjusts the buffer pointer and length, thereby avoiding a reverse
seek on the gzipped data stream.
I incorporated a suggestion from Matt Dillon which saved a little
bit of code in this fix.

was not the fault of the module code, nor FICL. The malloc code requires
sbrk() to return addresses that were at least 16 byte aligned. If the
Alpha loader happened to be 8 byte but not 16 byte aligned in length, then
you would get a zfree() panic at startup.
Incidently, this affected the i386 loader as well, and explains why
the static heap changed things and why jlemon had trouble when the bss
was not ending at a multiple of 8 bytes.
My fix is to 16 byte align it on all arches, even though the x86 version
only required 8 byte alignment (struct MemNode is smaller there). We could
page align it if we wanted to be paranoid, but it isn't presently necessary.
