# SYNOPSIS
#
#   AX_DIST_MSI([File])
#
# DESCRIPTION
#
#   Adds support for a msi (Microsoft Installer) dist target.
#
#   You must manually build the msi file yourself (probably from
#   another computer). But it will be added to the list of extra bin
#   dists and flagged for uploading (see ax_extra_dist.m4 and
#   ax_upload.m4 for details).
