Changes t1lib-5.1.0:

- Check against MultipleMasterFonts somewhat more tolerant, so that
  Type 1 Fonts automatically created from Multiple Master Fonts (e.g.
  using Mmpfb) should now be acceptable.

- The configure-machinery had been somewhat out of date and has been
  updated. The distributed configure script has been generated by
  AutoConf 2.59 and the redistributed libtool parts are taken from
  GNU libtool 1.5.10.

- Top-Level TeX-file in the doc subdirectory adapted to recent TeX
  systems' requirements.

- Added IsoLatin9.enc to distribution.

- Subsetting extended so that it works for SEAC-constructed composites
  even if no AFM composite character information is available

- Somewhat more intelligent defaults for subsetting when composite
  characters are included in the subset.

- Reallocation had been broken by relocation of internal StandardEncoding
  vector. This problem turned out on systems where realloc() actually
  returned a different pointer.

- Fix for outline code on 64bit systems. This involves a redefinition
  of the T1_PATHPOINT struct. This should be uncritical because for 32bit
  systems there is no difference, whereas on 64bit systems, this has never
  worked correctly before.

- DESTDIR support in Makefile.in by Volker Zell

- Support for XLFD font database format (in which the fonts' names appear
  in the first place on a line).

- Further Bug Fixes
