I recently downloaded the current version of cygwin on
2006-04-01 and got the following messages when running acloal:
--------------------------------------------------------------------
/usr/share/aclocal/libsmi.m4:8:
warning: underquoted definition of AM_PATH_LIBSMI

/usr/share/aclocal/libmcrypt.m4:17:
warning: underquoted definition of AM_PATH_LIBMCRYPT


/usr/share/aclocal/cppunit.m4:4:
warning: underquoted definition of AM_PATH_CPPU NIT
--------------------------------------------------------------------

This problem has been around for a long time, see
http://sources.redhat.com/automake/automake.html#Extending-aclocal

I am including below (for others) a bash script that I use to fix this (so
that one pays better attention to other warnings generated by aclocal).

The proper fix for this is to have the libsmi, libmcrypt, and cppunit
projects fix the macros.
