(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.)
