(free_to_unicode_table): * unicode.c (free_charset_unicode_tables): * win32.c (mswindows_read_link_1): Rename: xfree(VAL, TYPE)->xfree(VAL) Command used: gr 'xfree *\((.*),.*\);' 'xfree (\1);' *.[ch] Followed by grepping for 'xfree.*,' and fixing anything left. Rationale: Having to specify the TYPE argument is annoying and error-prone. It was originally put in to work around warnings due to strict aliasing but years and years ago I rewrote it in a way that doesn't use the TYPE argument at all and no one has complained since then. (And anyway, XEmacs is far from ever being in compliance with strict aliasing and would require far-reaching changes to get that way.)

/*
  The format of a fontname (as returned by fontconfig) is not well-documented,
  But the character repertoire is represented in an ASCII-compatible way.  See
  fccharset.c (FcCharSetUnparse).  So we can use UTF-8 for long names.

  Currently we have a hack where different versions of the unparsed name are
  used in different contexts fairly arbitrarily.  I don't think this is close
  to coherency; even without the charset and lang properties fontconfig names
  are too unwieldy to use.  We need to rethink the approach here.  I think
  probably Lisp_Font_Instance.name should contain the font name as specified
  to Lisp (almost surely much shorter than shortname, even, and most likely
  wildcarded), while Lisp_Font_Instance.truename should contain the longname.
  For now, I'm going to #ifdef the return values defaulting to short. -- sjt
