Description:
Found in the big (9.3Mb) Windows-Zip Source of Version 4.0.20a - 
while trying to compile the Sub-Project "libmysqld"

--------------------Konfiguration: libmysqld - Win32 Release--------------------
Linker-Vorgang läuft...
LINK : fatal error LNK1181: Eingabedatei "..\lib_release\myisam_tls.lib" kann nicht geoeffnet werden
Fehler beim Ausführen von link.exe.

Translation - thought meaning should be obvious:
LINK : fatal error LNK1181: File "..\lib_release\myisam_tls.lib" cannot be opened
Failure Executing link.exe

How to repeat:
Download the 4.0.20a big windows source package (9.3mb, MD5: 6398bfee4f2f4a82efff7a156c8782a2 )

unpack - open mysql.dsw with VC6;
Set "libmysqld" as active project an do a complete build of libmysqld.dll

once it reached the linker-Stage, the error occurs...

Suggested fix:
Under Settings -> tab "linker" -> object/library modules are given
(at the end of the list) following entrys:

..\lib_release\myisam_tls.lib ..\lib_release\myisammrg_tls.lib ..\lib_release\mysys_tls.lib ..\lib_release\strings.lib ..\lib_release\regex.lib ..\lib_release\heap_tls.lib ..\lib_release\innodb.lib ..\lib_release\bdb.lib ..\lib_release\zlib.lib

only that those libs with the _tls.lib ending are not created - 
instead the files without _tls are made - so the correct linkersettings should be
like

..\lib_release\myisam.lib ..\lib_release\myisammrg.lib ..\lib_release\mysys.lib ..\lib_release\strings.lib ..\lib_release\regex.lib ..\lib_release\heap.lib ..\lib_release\innodb.lib ..\lib_release\bdb.lib ..\lib_release\zlib.lib

Thank you for the bug report.I was able to repeat with Windows source built
from latest BK tree:

unireg.cpp
Generating Code...
Linking...
LINK : fatal error LNK1181: cannot open input file "..\lib_release\myisam_tls.lib"
Error executing link.exe.

libmysqld.dll - 1 error(s), 2 warning(s)

Additional Info:
Currently the work-around is to build before the missed libraries
with the Batch Build selection option.

Not sure yet if simply removing the lines referring to the *_tls.lib files is the correct approach.

These libraries do exist, when the compile is performed a second time. To me this looks like a wrong build dependency instead - the linker should not attempt to link against libraries that have not been built at that point. Still investigating...

It seems like this modification (to link the libmysqld release library against the "TLS" versions of these other libs) was done on purpose by Monty - I am waiting for feedback from him about the rationale for this change. You proposed fix looks correct to me, I just want to verify that there is not a special reason for this. As a workaround, you can simply build these TLS libs before building the libmysqld project.

According to Monty, it is actually intended to link mysqld against the _tls.lib files, otherwise the resulting binary would not work. The main problem is that the VC++ compiler can only create dependencies for projects within the same configuration. libmysqld and mysys_tls are in different configurations and can thus not be made dependable. So he currently does not see a way to work around this restriction in how the Microsoft compiler works.

I will resolve this bug as "Won't fix" for the time being - there is no workaround for this available at the present time.
