Cygwin Make bash command not found
Solution 1:
While instaling (updating) check 'Devel' to 'Install', it will install a lot of MB but helps. I don't have time to check which exacly I (we) need.
Solution 2:
You probably have not installed make. Restart the cygwin installer, search for make, select it and it should be installed. By default the cygwin installer does not install everything for what I remember.
