Introduction
------------
emxfix01.zip is a fix package for emx 0.9c.
If you are a programmer who uses emx for creating applications,
install emxfix01.zip. If you just use applications which use emx,
install the emxrt.zip corresponding to emxfix01.zip (see the ZIP
comment). You don't have to install both.

In consequence, emxfix01.zip can be distributed only if distributed
with emxsrcr.zip.
Caveat
------
Do not install this fix package unless you have installed emx 0.9c.
It does not work with any other release of emx. Do not install
emxfix01.zip if you have already installed a later fix package.
Problems solved by this fix package
-----------------------------------
[emxfix01.zip]
o pmgdb cannot cope with invalid display expressions.
o emxupd displays a bogus warning ("emx 0.9c or later required").
o ld does not correctly handle references from the data segment to
imported symbols.
o In <netinet/ip.h>, the test for TCPIPV4 is backwards.
o tzname[0] and tzname[1] are NULL if TZ is invalid.
o timezone is not correctly set.
o TZ=XYZ (without offset) is not accepted.
o stat(), opendir() etc. trap if the file name is "/" or "\\".
Features added by this fix package
----------------------------------
[emxfix01.zip]
o emxbind now can export variables from DLLs (that is, symbols from
the .data and .bss segments).
o emxexp now supports long member names.
Revision indexes
----------------
emx.dll 50
emx.exe 50
emxio.dll 50
emxlibc.dll 50
emxlibcm.dll 51
emxlibcs.dll 51
emxwrap.dll 50
Installing this fix package
---------------------------
1. Stop all processes which use emxlibcm.dll or emxlibcs.dll. Use
emxload -qw
to stop preloaded programs under OS/2.
2. Unpack emxfix01.zip or emxrt.zip (see introduction) in the root
directory of the drive where you have installed emx:
cd \
unzip -o emxfix01 (or `unzip -o emxrt')
Do not use the -f and -u options of unzip -- the time stamp of
header files has not been updated.
If you get an error message such as
error: cannot create emx/dll/emx.dll
about not being able to create a DLL file, create a temporary
directory and run emxuzdll.cmd in that directory, giving the path
name of emxfix01.zip or emxrt.zip and the path name of the emx DLL
directory on the command line:
mkdir \emxtmp
chdir \emxtmp
emxuzdll a:\emxfix01.zip c:\emx\dll
chdir ..
rmdir emxtmp
This will replace the DLLs in c:\emx\dll with the DLLs in
emxfix01.zip even if the DLLs are in use. The new versions of the
DLLs become active as soon as the last process referencing them is
terminated, or on the next reboot. Therefore, you should reboot
after running emxuzdll, otherwise you won't know if and when the
new versions become active. (Actually, you don't need a temporary
directory, any directory not containing any DLL files will do.)
To take advantage of the library fixes, relink your programs.
You should keep the file \emx\doc\emxfix01.doc as it shows what fixes
you have installed.
