MSVC build: Drop crypt implementation for MSVC
We are actually not using the crypt() in GDK-Broadway for quite a while, so the code implementation for MSVC is actually not used. So, it's time to get rid of this.

* The source in this file is heavily borrowed from the crypt3.c file

|

* The code below has been cleaned and compiles correctly under, gcc,

* lcc, and Borland's bcc C compilers. A bug involving the left and
|

* right halves of the encrypted data block in the widely published
|
||||
* crypt3.c source has been fixed by this version. All implicit register
|
||||
* declarations have been removed, because they generated suboptimal code.
|
||||
* All constant data has been explicitly declared as const and all
|
||||
* declarations have been given a minimal scope, because I'm paranoid.
|
||||
*
|
||||
* Caution: crypt() returns a pointer to static data. I left it this way
|
||||
* to maintain backward compatibility. The downside is that
|
||||
* successive calls will cause previous results to be lost.
|
||||
* This can easily be changed with only minor modifications to
|
||||
* the function crypt().
