Isn't the current definition of BASE_PURESIZE too large?

  #define BASE_PURESIZE (1430000 + SYSTEM_PURESIZE_EXTRA + SITELOAD_PURESIZE_EXTRA)

I looked at the values of pure_size vs pure_bytes_used in several
builds on several platforms, and I see that we are wasting at least
130KB:

    MS-Windows:
    (gdb) p pure_size
    $1 = 1480000
    (gdb) p pure_bytes_used
    $2 = 1357888

    64-bit GNU/Linux (--without-x):
    (gdb) p pure_size
    $1 = 2383333
    (gdb) p pure_bytes_used
    $2 = 2015813

    64-bit GNU/Linux (with X):
    (gdb) p pure_size
    $1 = 2383333
    (gdb) p pure_bytes_used
    $2 = 2193049

    MS-DOS:
    (gdb) p pure_size
    $1 = 1440000
    (gdb) p pure_bytes_used
    $2 = 1275442

GNU/Linux without-X is the extreme example: it wastes 370KB.

How about reducing the 1430000 number above?

I get the warning message "Building Emacs overflowed pure space".  Assuming
this is related to decreasing BASE_PURESIZE, the argument for keeping it to a
minimum for computers with little memory against the inconvenience of
repeatedly tripping over it, is completely lost on me.  Especially with a
development version (as we could. presumably, just pare it back prior to
release).
