Fiew bug fixes patch.

[Andrey Kulikov]

All patchs for version 1.2.1

1.
One disagreeable bug:
In constructor of ost::Thread parameter class variable "stack"
overriten with parameter variable with the same name.
As a result can't be created any thread withot any errors or
diagnostic.
(In my programs i'l always use prefixes "m_" (member) or just "_" for name of
the local class variables, and prefix "a_" (argument) for all
variables passsed as a parameters to any functions. And it prevents
from such very difficult to debug errors)

2.
I'l add to win32 config.h one define "CCXX_NO_DLL".
If this macro defined, cc++ can be compiled as a static library.
In comments in thread.cpp was written:
 "This project cannot be compiled as a static library. Some
 implementation stuff require DLL"
And if it's "Some implementation stuff" is not necessary, and other
functionality still necessary, it is possible to use this macro for
compiling cc++ as a static library. (But some changes in projects file
is necessary).

Other question is what exactly "implementation stuff" require DLL?
This information is necessary for prevent unexpectable revelation of
fine features. :)
In my programs, which intensively useв ost::Thread i not find any
difference between DLL and nonDLL linkage.

3.
Underground of ost::Mutex in win32.
I implement suggestion of David 
(http://lists.gnu.org/archive/html/bug-commoncpp/2004-06/msg00027.html)
and add to win32 config.h two macros:
MUTEX_UNDERGROUND_WIN32_MUTEX and MUTEX_UNDERGROUND_WIN32_CRITICALSECTION
An one time can be defined only one of this two macros.
It's indicate, what must be used for background of ost::Mutex on
win32: kernel object "Mutex" or win32 critical section.


All changes compiled with VS2003 and tested on WindowsXP.
