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.)
