Warning about 1.5.0 (maybe I did something wrong,
	maybe I didn't......)

I was able to extract/patch all the 1.5.0 postings
to match the crc's except a few of the
doc and man files, and have  built new library and kernel,
mm, fs, and tools.

Unfortunately, when I booted the new kernel, the superblock of my
hard disk partition was no longer readable to
1.5.0 and protected mode 1.3.  BE CAREFUL!

I had been running protected mode 1.3, and have had ZERO problems
with the minix partitions due to minix.  I find it suspicious
that the first time I boot minix 1.5.0 that the superblock got 
destroyed.  Only the superblock of my 'root' partition (/dev/hd6)
was corrupted, I was able to access my /usr partition (/dev/hd7 ok)
using 1.3 later, but no luck yet with /dev/hd6.

I just wanted to WARN other's to be careful, but hopefully they
will not have the same problem.  I would look into this more,
but I felt that it warented a QUICK posting immediately in case
there was some REAL problem.  If not, sorry for the scare.

Here are some other observations about 1.5.0.

I noticed by comparing the source files mentioned in ast's liborder
and the lib files posted, that the library functions
memmove.s, strcol.s and strxfrm.s are not posted.

Also the run script for posix does not include the _exit.c ( it
should include [_a-z]*.c instead of just [a-z]*.z.

Also some makefiles reference /lib/libc.a and others refernece /usr/lib/libc.a

more later.....
