Because Win32 is built with cygwin, the cygwin1.dll version it is bundled
with GrADS has to match the version of the other Cygwin you have installed.
Version 1.8sl11-xwin32.exe is more than 5 years old and it may be tricky to
get it to work with a newer version of Cygwin. Here are my recommendations:

1) Install the most recent v1.9-rc1 Win32 Superpack from

   You can find some more info about this release here:

2) If you prefer to stay with v1.8, try deleting or renaming the
"cygwin1.dll" that came with GrADS with the one in your cygwin release. Very
important: *reboot* and start GrADS again.
