Files sysdep.[ch] are now in ${MACHINE_ARCH} subdirectory. Internal
#if's used to identify the platform where removed.
Make rule for target testmain was greatly simplified, because it was
easier simplifying it than changing it to support the new location of
sysdep.[ch].
(a repo-copy was done on sysdep.[ch], of course)
-fschedule-insns as it wasn't such a big win with 2.95 after all.
Add the *BIG* win "-mpreferred-stack-boundary=2" optimiztion submitted by
Dima. GCC 2.95 ensures the stack frame is always properly [opitimally]
aligned by surrounding every function call by code simular to
"addl $-12, %esp" / "addl $12, %esp". Here we need the reduction in space,
with speed not an issue.
All Makefiles now use MACHINE_ARCH for the target architecture.
Unification is required for cross-building.

fixed typo: MACHINDE -> MACHINE_ARCH
Remove some printf() calls, reduce size of buffers, and abbreviate
some strings.
Hopefully the boot people will fix this spamage after the cut over to
Gcc 2.95.2 as the system compiler.
either one gives us an additional 32 bytes of additional space available
when using EGCS 1.1.2. With GCC 2.95.2 -fforce-addr gives us 12 more bytes,
and adding -fschedule-insns gives us an additional 4 bytes.
Mike says the whole idea of a current device was a bad idea in first place,
and will be doing away with currdev.
Anyway, people are not supposed to even notice this. :-)
Memory" called as function 0x87 of interrupt 0x15. Since the Mylex RAID
adapter's BIOS used this function to access memory (actually PCI bus
space) beyond 16 MB, this patch also allows BTX to address all 4 Gig of
possible address space on i386+. Since the loader does not have room for
4 MB of page tables, this was done by turning off paging.
Paging was turned off via a compile time setting which defaults to off.
To enable paging, simply define the make variable PAGING.
rnordier might want to clean this up later.

This happened to be my first "for real" broken world. I had broken
it once before, but nobody noticed, so it didn't count.
So, how do I get the "I broke world and all I got was the lousy t-shirt"
t-shirt?
- Make as much of the makefile for each of the three flavours
(disk, CDROM, net) common.
- Special-case the libalpha startup module on its use in boot1, not
the other way around.
- Build the loader out of a "loader" directory
