GnuPG for Win32

[Soh Kok Hong]

Dear all,

The patch that I am suggesting builds a Win32 executable (ie. no cygwin
DLLs needed) using the CYGWIN's mingw32 tools.  I did not use the mingw32-cpd
stuff because it is rather old and does not include winsock2 - winsock2 is
required in building gnupg for Win32.

You need to run autoconf (by running "scripts/missing --run autoconf") to
rebuild the configure script first.

The changes are as follows:

1. acinclude.m4 & aclocal.m4
- patch to set ac_cv_sys_symbol_underscore to yes for mingw32 target

2. configure.ac
- Added AC_PROG_RANLIB - this was missing.  In real unix targets,
this variable is added because of AM_GNU_GETTEXT which performs
lots of tests - one of which is to set AC_PROG_RANLIB.  In mingw32
target, this did not get set because try_gettext set to "no", hence
AC_PROGR_RANLIB never gets set.

- added a check for presence of strcasecmp function.  Again, the reason
this did not get checked is because of the AM_GNU_GETTEXT problem.

3. cipher/rndw32.c
- forced include of winioctl.h.  This is needed to include the
DISK_PERFORMANCE structure definition.
