FWIW, starting with this change, I had to set SITELOAD_PURESIZE_EXTRA
also[1] on the machine (SUSE 10.0 [2]) on which it wasn't necessary
until some weeks before this change.

Unless we find (and fix) the reason for the different pure space
requirements, it would be good to increase BASE_PURESIZE to an amount
that allows building Emacs without an overflow on most machines, I
think.

Bye, Reiner.

[1] I still need to increase it on the machines as reported
    previously[3].  On i686 (2x Intel Xeon (2.40GHz)) and x86_64 (AMD
    Athlon 64 3500+):

$ gcc --version
gcc (GCC) 3.3.4 (pre 3.3.5 20040809)
[...]
$ cat /etc/SuSE-release 
SuSE Linux 9.2 (i586)         [... or x86_64 resp.]
VERSION = 9.2

[2] i686 (Intel(R) Pentium(R) M processor 1500MHz):
$ cat /etc/SuSE-release 
SUSE LINUX 10.0 (i586) OSS
VERSION = 10.0
$ gcc --version
gcc (GCC) 4.0.2 20050901 (prerelease) (SUSE Linux)
