Hi!

First the good news:
If you have gotten the 1.5.3 sources you can upgrade to ST 1.5.5
using the postings from ast.
Everything should work except ps. Below is an unofficial fix to ps.
This fix will be made official by ast (I hope) in the next version.`
Please keep your original version of ps.c

For those people stuck at the 1.5.0 to 1.5.3 upgrade, I can tell that
you can upgrade your lib with the PC 1.5.3 postings. The same holds for
mm, fs, test, commands. 
Always first apply ast's postings. Then minde.

Generally speaking the PC and ST versions are equivalent with the
exception of the following things:
kernel (I still haven't received the official 1.5.x kernel from ast, so
	you must use the 1.5.0 version for the time being).
lib/atari, commands/atari	(atari specific, extra)
lib/ibm, lib/string, commands/ibm	(PC specific, of no use on the ST)
include/a.out.h ST has a different version due to byte ordering in words
include/out.h	ST specific
tools		PC specific, ST has sttools directory

It is my intention to keep the sources as much as possible equivalent
between PC and ST. This cuts down the maintenance effort, and makes it
possible that we all use the same book.

regards, Frans Meulenbroeks.

PS:
If you encounter a bug I appreciate a posting or mail.
notice though that regularly I cannot reply due to weird addresses
or bounced messages from mailers.
If you encounter a problem before complaining please check first if the
crc of your source is equivalent with the one posted by ast, and if your
system is up to date (see ast's crc list for crc's for mm and fs, and
the one I posted about a month ago for the kernel)
