Finding unnecessary (K&R compat) casts

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

We have all these now unnecessary casts previously included for K&R
compatibility, e.g. the return type of allocating functions or the
arguments of memcpy, etc.  Basically stuff possibly declared as PTR
either now or in the past.

I wanted to generate a complete list of such functions to know where
to look for zapping spurious casts.  So far I have these for return
values:

(m|c|re|xm|xc|xre)alloc
xmemdup
alloca
htab_fin(d|d_slot|d_with_hash|d_slot_with_hash)
ggc_[a-z_]*alloc[a-z_]*

for argument casts I have these functions:

mem[a-z]+

Can anyone think of anything else?
