# system check;
# for now, let's enforce Cygwin 32-Bit as the container for wsltty
# just in case there is a 32-Bit WSL released (-> 32 bit), and to ensure 
# the path name drag-and-drop adaptation works (-> cygwin, not msys)

check:
	# checking suitable host environment; run `make pkg` to bypass
	# check cygwin (vs msys) for proper drag-and-drop paths:
	uname | grep CYGWIN
	# check 32 bit (vs 64 bit) to ensure 32-Bit Windows support, just in case:
	#uname -m | grep i686
	# check 64 bit (vs 32 bit) to provide 64-Bit stability support:
	uname -m | grep x86_64
