$ cygcheck -f /etc/postinstall/fontconfig_dtd.sh
libfontconfig-common-2.13.1-1
$ cygcheck -f /usr/bin/xmlcatalog
libxml2-2.9.10-1
$ cygcheck -f /usr/share/xml/fontconfig/fonts.dtd
libfontconfig-common-2.13.1-1
$ head /etc/postinstall/{fontconfig_dtd,libxml2}.*
                   ==> /etc/postinstall/fontconfig_dtd.sh.done <==
if [ -x /usr/bin/xmlcatalog ] ; then
    /usr/bin/xmlcatalog --noout --add "system" "fonts.dtd"
/usr/share/xml/fontconfig/fonts.dtd /etc/xml/catalog
fi

==> /etc/postinstall/libxml2.sh.done <==
if test ! -f /etc/xml/catalog; then
        /bin/mkdir -p /etc/xml
        /usr/bin/xmlcatalog --noout --create /etc/xml/catalog
fi
$ llgo /{etc/xml/,usr/bin/xml}catalog /usr/share/xml/fontconfig/fonts.dtd
/etc/postinstall/{fontconfig_dtd,libxml2}.*
-rw-r--r-- 1  152 Jul 28  2019 /etc/postinstall/fontconfig_dtd.sh.done
-rw-r--r-- 1  118 Mar 25  2019 /etc/postinstall/libxml2.sh.done
-rw-r--r-- 1 1.2K Jul 30  2019 /etc/xml/catalog

So check the existence of all the files and all the postinstall scripts,
re-execute the latter if necessary, re-install packages if necessary to make
repairs, and ensure the postinstall scripts are renamed with .done appended when
successfully completed.
