fee94d14ba README: Add gcc-wlink and gcc-wrc to install instructions. 
W/o them, gcc will default to ILINK which is not supported (and most likely, is absent from PATH anyway).

4202248449 libstdc++: Force OS/2 DLL name base to be stdcpp instead of stdc++. 
This is both for backward compatibility with previous builds and
to avoid "dangerous" symbols (+) in the DLL name.

79d1856968 Revert "OS/2: Enable C99 stuffs in C++11" 
This reverts commit 08fda42141.

These hacks are not necessary any longer since the respective fixes have been applied to LIBC, see
7f3d308fd6 and
ac12fd8873.

e76e0e5f37 Remove all configure scripts and other generated Autotools files. 
On platforms that are not officially supported by GNU Autotools (like OS/2)
it is necessary to generate configure and other related stuff using platform-specific
Autoconf and Automake to make the build succeed. A script autoconf.sh added
by this commit does that.

Note that it's necessary to remove pre-generated upstream versions of these files
from Git completely in order to avoid seeing multiple differences resulting from
different versions of Autotools (and also to save some space - configure files
are huge).

This commit also adds a few minor bits to configure.ac/Makefile.am of a few
projects to help autoconf.sh do its job properly.

Needed for #2.

This is necessary on platforms where it is .exe (OS/2 or Windows).

Note that it didn't affect Windows because fixincl is not run there at all.

b833c1e35a OS/2: Synchronize EMX code with recent Windows NT (Cygwin) changes. 
This commit contains a lot of changes in many EMX-related sources for several years.
Unfortunately, there are not many notes on the changes from the author so it's really
too much of work to split them in smaller pieces.

Also note that this patchset was brushed up by the committer (several questionable changes
and leftovers removed, several minor issues are fixed).

08fda42141 OS/2: Enable C99 stuffs in C++11 
C++11 supports some C99 features. However OS/2 kLIBC headers do not
support them well.

To workaround, define some feature test macros as built-in. They are

    __STDC_CONSTANT_MACROS
    __STDC_LIMIT_MACROS
    __LONG_LONG_SUPPORTED

Especially, __LONG_LONG_SUPPORTED enables _GLIBCXX_USE_C99 feature in
libstdc++-v3, which use -std=c++98 to test C99 features in C++.
