I have code for a database I am porting to Cygwin.
Part of that code is a clearenv() then a couple of setenvs. There is
an ifdef for Cygwin, as it doesn't implement clearenv. It just sets
environ = NULL. Well--that really breaks setenv! It returns a "Bad
Poniter" error (-1).
What is the correct way to clear environment variables in Cygwin?

not tested but it seems Cygwin is not the only platform
with problem on environ = NULL
environ = calloc(1, sizeof(*environ))
