# func_to_host_path arg
#
# Convert paths to host format when used with build tools.
# Intended for use with "native" mingw (where libtool itself
# is running under the msys shell), or in the following cross-
# build environments:
#    $build          $host
#    mingw (msys)    mingw  [e.g. native]
#    cygwin          mingw
#    *nix + wine     mingw
# where wine is equipped with the `winepath' executable.
# In the native mingw case, the (msys) shell automatically
# converts paths for any non-msys applications it launches,
# but that facility isn't available from inside the cwrapper.
# Similar accommodations are necessary for $host mingw and
# $build cygwin.  Calling this function does no harm for other
# $host/$build combinations not listed above.
#
# ARG is the path (on $build) that should be converted to
# the proper representation for $host. The result is stored
# in $func_to_host_path_result.
