-dnl - suport for extra-verbosity
+dnl - support for extra-verbosity
dnl - ordinary libs are handled separately from X libs (might be a mistake)
dnl - various random kludges (e.g. -with-dnet=no)
dnl redefine AC_CHECK_LIB in accordance with our own value of ac_link
dnl Add in extra kludgy check to support with_dnet=no
-dnl Add in extra LDFLAGS arg, which PRECEDE libs
+dnl Add in extra LDFLAGS arg, which PRECEDES libs

with_tty=""

with_dnet=""
-pdump="no"
+dnl pdump now defaults by opsys

dnl dragndrop is still experimental. When it is stable, comment out the following line:
with_dragndrop="no"
-dnl I think this is mandated by IPv6 standards.
