Alternatively, the crypt libraries in GNU libc have been ported to Cygwin.

Win9x does not correctly report C<EOF> with a non-blocking read on a
closed pipe. You will see the following messages:
- But it also returns -1 to signal EOF, so be careful!
- WARNING: you can't distinguish between EOF and no data!

=item * Cygwin vs. Windows errors
may result on a DLL baseaddress conflict. The internal cygwin error
looks like like the following:
- 0 [main] perl 8916 child_info_fork::abort: data segment start: parent
- (0xC1A000) != child(0xA6A000)
+ 0 [main] perl 8916 child_info_fork::abort: data segment start:

or:

- C:\cygwin\bin\cygsvn_subr-1-0.dll to same address as parent(0x6FB30000) != 0x6FE60000

It helps if not too many DLLs are loaded in memory so the available address space is larger,
e.g. stopping the MS Internet Explorer might help.
Use the perlrebase or rebase utilities to resolve the conflicting dll addresses.
The rebase package is included in the Cygwin setup. Use F<setup.exe>
-from L<http://www.cygwin.com/setup.exe> to install it.
