TS implementation of crypt() for windows

HI!

Please find a new implementation of the crypt function for windows.
The current code is not thread safe and suffer from a security issue
since too long (we count in years now :P).

Here is the patch:

http://pierre.libgd.org/patches/crypt_r_win32.patch.txt

It uses the CryptoAPI for the MD5 version and a classic crypt_r
implementation for DES to keep BC.  I would have liked to use the
cryptoAPI as well but the crypt's DES is not standard.


Before I apply this patch, I would like to know if you see any issue :)

Thanks for your feedbacks,

Cheers,
