Don't use Gnulib's explicit_bzero on MS-Windows
This is a preventive change, since Gnulib was recently changed
its explicit_bzero to call SecureZeroMemory on MS-Windows,
disregarding systems older than XP, which didn't have it.
* src/w32.c (explicit_bzero): New function.
* nt/mingw-cfg.site (ac_cv_func_explicit_bzero): Avoid using the
Gnulib replacement for explicit_bzero.
* nt/inc/ms-w32.h (explicit_bzero): Add prototype.
