compiling on windows for x86

[Ali Rostami]

Hi every body, I started to use  cpputest_starter_project in my project on my windows 11. At first I compiled it with docker but as it was too slow -because of using WSL 2- I decided to compile for x86 CPU it locally.

Finally I could do it by executing this command from cpputest_build folder in cpputest:

cmake -G "MinGW Makefiles" -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/clang+mingw-win32.toolchain.cmake ..

In the makefile of unit-tests (cpputest_starter_project) I also added these flags:

CPPUTEST_CPPFLAGS += -m32

CPPUTEST_LDFLAGS += -m32

At first, it was complaining about not finding libCppUTest.a and libCppUTestExt.a, so I copied them to cpputest/lib and seemed it found them and now here is the result:

$ make -C ./unit-tests/
make: Entering directory 'C:/microcontroller/blahblah/unit-tests'

Running your_tests
..........
OK (10 tests, 10 ran, 91 checks, 0 ignored, 0 filtered out, 2 ms)

Are these warnings problematic or I should not care? Any suggestion on how I can solve them? Could I do anything better?
