What is MinGW?

I need bash and posix environment!

I already have a /usr/bin/cygwin1.dll on the Windows 8 target system.
Do I have to replace it?

This is what I first did:
Transfered the 32 bit cygwin with my self compiled binaries to the 64 bit
Windows 8. But then I was not able to use perl, I got a MOT of these errors:

         0 [main] perl 4232 child_info_fork::abort: address space needed
   by 'Encode.dll' (0x370000) is already occupied
   Can't fork, trying again in 5 seconds at /client/bin/fexsend line 106.
         1 [main] perl 7720 child_info_fork::abort: address space needed
   by 'Encode.dll' (0x370000) is already occupied
   Can't fork, trying again in 5 seconds at /client/bin/fexsend line 106.
         1 [main] perl 5484 child_info_fork::abort: address space needed
   by 'Encode.dll' (0x370000) is already occupied
   Can't fork, trying again in 5 seconds at /client/bin/fexsend line 106.

See my mail:

These error are gone after I replaced the 32 bit cygwin with a 64 bit
cygwin installation.
