By hardcoding os=Msys gcc=arm-none-eabi-gcc exefile=arm-none-eabi-gcc inside incdir.sh time tools/incdir.sh -s arm-none-eabi-gcc/home/Schock/nuttx/nuttx/include reduced from 180ms to 40ms.
Overall, this reduced build time from 30min to an acceptable 6min. So incdir.sh is taking too much time in MSYS2 Isn't there a possibility to cache the results of the system checks inside incdir.sh?

That is a mystery.
