On my Athlon 64, running 32-bit Linux, I'm still getting two
source-vs-semantic errors

Ok, turns out this is due to a change in the PHP api:

edsko@slash:~$ /opt/php-5.2.0/bin/php -r "var_dump(0x100000000);"
int(2147483647)
edsko@slash:~$ /opt/php-5.2.1/bin/php -r "var_dump(0x100000000);"
float(4294967296)

Now we need to make a policy decision...

The decision was to change to the 5.2.1 behaviour, since it is cleaner. 

Bug 16 discusses a longer term fix for this sort of problem.

I removed the strange edge cases for hexadecimal ints, which have mercifully 
been
fixed to work in an intuitive way in PHP 5.2.1.
