Running `build-aws.ps1` on windows fails with vagrant 2.2.18

[matt-richardson]

Running build-aws.ps on window 11, using vagrant 2.2.18 fails with a nasty error: conflicting types for 'gettimeofday'

PS > .\build-aws.ps1 -SkipPester
Vagrant installed - good.

Vagrant failed to properly resolve required dependencies. These
errors can commonly be caused by misconfigured plugin installations
or transient network issues. The reported error is:

Solution Hacky workaround is to edit C:\HashiCorp\Vagrant\embedded\mingw64\x86_64-w64-mingw32\include\sys\time.h and change:

#ifndef _GETTIMEOFDAY_DEFINED
#define _GETTIMEOFDAY_DEFINED
int __cdecl gettimeofday(struct timeval *__restrict__,
                         void *__restrict__  /* tzp (unused) */);
#endif

to

#ifndef _GETTIMEOFDAY_DEFINED
#define _GETTIMEOFDAY_DEFINED
//int __cdecl gettimeofday(struct timeval *__restrict__,
//                         void *__restrict__  /* tzp (unused) */);
#endif
