If you're modifying the environment, you should be using putenv or setenv
to do so. If those are truly not working then you should be able to
write a simple test case to demonstrate the problem.
If you are using the Windows API to set environment variables, then it
is possible that an execed cygwin process will not recognize them. You
do need to use the cygwin *env functions for manipulating the cygwin
environment.
