Microsoft insists on trying to add an extension to the name of the binary unless it has an explicit '.' as its last character. Use the internal spawnveq() instead, as it handles various quirks like the above. Adds 16-32 bytes.

Allow building on somewhat older toolchains.

The shell in busybox-w32 was unable to run such programs. When a program fails to run with ERROR_ELEVATION_REQUIRED, try again using ShellExecuteEx() with the 'runas' verb to give it elevated privileges. Adds 272-288 bytes.

The issue was introduced by commit 0475b7a64 (win32: convert exit codes). This passed a POSIX error code to the exit() in wait_for_child() so a parent was unable to detect when its child was interrupted. Pass the Windows exit code to exit() instead. Work around the changes introduced by commit 790e377273 (win32: revert 'don't set error mode').
