PostScript fonts path search broken in configure

[David Starks-Browning]

Greetings,

This is a2ps-4.13b.tar.gz dated 8 Mar 2000 from
<ftp://ftp.enst.fr/pub/a2ps/>.

This bit of configure code that looks for PostScript fonts paths is
incorrect:

> echo $ECHO_N "checking for PostScript fonts path... $ECHO_C" 1>&6
> echo "configure:8448: checking for PostScript fonts path" 1>&5
> # Try to find some PostScript fonts.
> # Find out if ghostscript is installed
> ac_psfont_path=
> for ac_dir in /usr/local/ghostscript/fonts \
>   /usr/local/share/ghostscript/fonts;
> do
>   if test "cd $ac_dir 2>/dev/null && echo *.afm"; then
>     ac_psfont_path="$ac_psfont_path:$ac_dir";
>   fi
> done
> if test -n "$ac_psfont_path"; then
>   PSFONT_PATH=`echo "$ac_psfont_path" | sed -e 's/^://'`
> fi
> 

Specifically, this test:

>   if test "cd $ac_dir 2>/dev/null && echo *.afm"; then

is successful even if $ac_dir does not exist.  I've tried some
variations on how this quoted, which get the correct answer on Linux
and IRIX, but crash configure on Compaq and Solaris.  Even if that
worked, there is no provision to find anything other than
/usr/local/ghostscript/fonts or /usr/local/share/ghostscript/fonts,
which is not very useful.  (Ours happen to be in
${prefix}/share/ghostscript/fonts, for example, and ${prefix} is not
/usr/local.)

Before I look harder at this, perhaps you could tell me how the
PSFONT_PATH is used, and whether it's worth getting right.

Thanks,
David
