Without specifying -g CONFIG_HOST_LINUX is assumed.
This worked well in the past with MSYS2.
But I will try -g later today.
Not if CONFIG_HOST_WINDOWS=y in the defconfig file. That is what is set
in stm32f4discovery:nsh:
$ grep -r CONFIG_HOST
boards/arm/stm32/stm32f4discovery/configs/nsh/defconfig
CONFIG_HOST_WINDOWS=y
I also double checked Xiang's recommendation using this patch:
$ diff -u boards/arm/stm32/stm32f4discovery/scripts/Make.defs .

That also gives a smaller, but consistent improvement in build time:
BEFORE:
time make
real 3m35.242s
user 0m26.620s
sys 1m9.932s
time make -j
real 0m47.548s
user 0m30.717s
sys 1m45.736s
AFTER:
time make
real 3m14.522s
user 0m21.474s
sys 0m56.380s
time make -j
real 0m46.532s

Again, that is using Cygwin on 32Gb Rizen 5 3600
