The common cache is a good suggestion, although I'd rather not rely on my
users to do that. I couldn't tell if your autogen pointer was intended to be
an example of this, or an alternate suggestion. autogen-5.3.8/configure.in
has this:
ac_configure_args="$ac_configure_args --enable-snprintfv-convenience"
...
AC_CONFIG_SUBDIRS(snprintfv)
Looking at the generated configure, this does seem like it'll work fine.
Yet another possible solution I thought of is to use the fact that
AC_ARG_VARs pay attention to environment variables, e.g.:
export foodir
AC_CONFIG_SUBDIRS(libfoo)
In fact, I think one could argue that AC_ARG_VAR should always do such an
export. This method doesn't work very naturally for --enable switches, though.
Anyway, thanks for the suggestions!
