CRYPT package for MinGW64/32

[Boszormenyi Zoltan]

Hi,

I created a package for cryptographic functions as found in
http://gnuwin32.sourceforge.net/packages/crypt.htm . You can get it from
http://www.kortancegyesulet.hu/private/zoltan/mingw-crypt-2.14-1.fc16.src...

Implementation details:

- The main crypt-2.14.tar.gz source is only a skeleton that contains
  configure.ac, Makefile.am, etc.

- The secondary source file (crypt.tar.gz) is the crypt directory
  from glibc-2.14.90-19 SRPM as in Fedora 16, you can compare them.
  GNUWin32's crypt.dll is a modified source from GLIBC 2.2.5.

- crypt-mingw.patch contains
    - 3 necessary private headers from glibc:
      sysdeps/i386/bits/byteswap.h
      sysdeps/x86_64/bits/byteswap.h
      sysdeps/x86_64/bits/wordsize.h
    - a naive implementation for stpncpy(3) as the algorithm is described
      in the man page
  and modifies the crypt source itself in a minimalistic was so it can
  compile standalone (e.g. there is no weak_alias(), and __THROW)
  and without warnings on both mingw32 and mingw64.

The result is libcrypt-1.dll (NOT crypt.dll as in GNUWin32), so when GLIBC
adds more crypthographic functions, the library version can increase.
All test programs (md5test.exe, md5c-test.exe, sha256test.exe,
sha256c-test.exe, sha512test.exe, sha512c-test.exe, ufc.exe) report
success with 0 return code.

Best regards,
