Oh awesome, I am sooo grateful.

Hello,
building on Windows is at least difficult and it takes ages (about 10
hours for a build on msys2 even if I provided a lot of cores to the VM).
It seems that you were right to suspect that the change might make
trouble (at least in one of the four cases that I tested). I don't post
a patch for the manual at the moment because I didn't manage to build a
complete toolchain yet.
I'll continue to investigate the problems but it will take a bit longer
because every test needs horrible long. An intermediate report:
All tests have been done with rtems-source-builder 5 branch with my
additional patch.
== Results on cygwin
Packets mentioned in the manual:
- gcc4-core Does not exist.
Installed gcc-core instead
- gcc4-g++: Does not exist.
Installed gcc-g++ instead
- mingw64-x86_64-g++ does not exist.
Installed mingw64-x86_64-gcc-g++ instead
- mingw-zlib-devel: Does not exist.
No replacement found.
- zlib-devel is now at "Libs"
- I had to install libreadline-devel and libreadline7 in the testing
version 8.1-1. Otherwise the build stopped with the information that
system readline isn't recent enough.
- The packet "python" doesn't exist. It's now either python2 or python3.
I tried both:
For python2 I installed python2 and python2-devel.
For python3 I removed python2* and installed python3 and python3-devel.
In both cases, the build system detected the correct python. But I
received errors like the following in the log:
`````````````````

unavailable.

I suspect that I would need a mingw64-x86_64-python2/3. But that packet
does not exist.
Any hints what I could try?
== Result on mingw
Beneath the packets in the manual, I had to install flex.
First test was with python2. That is where my patch made problems: If I
installed "python" (which is python3) like said in the manual, gdb
detected python3 and wanted to use that (due to my patch). I only
install mingw64/mingw-w64-x86_64-python2 like said in the manual so that
didn't work. If I removed "python" again, I had to use a workarround for
RSB to work (PYTHONIOENCODING=UTF-8 ../source-builder/sb-set-builder
--prefix=/opt/rtems/5 5/rtems-sparc) and then the first 10 hours build
fine (gdb, gcc, ...) but the build stopped when building rtems-tools
with the following error in the log file:
`````````````````

`````````````````
Which somehow makes sense because I removed the "python" packet.
If I tried with python3 instead (removed
"mingw64/mingw-w64-x86_64-python2" and added "mingw-w64-x86_64-python"
and "python") I didn't need the workarround with the PYTHONIOENCODING.
But the build stopped a lot earlier with the following message in the log:
`````````````````

Seems that somewhere a opening quotation mark is added where it
shouldn't be.
