64bit check fails on aarch64

[zvidrih]

SnappyMail 2.24.4 fails with

[301] Your PHP version is 32bit, 64bit is required!

on 64bit ARM architecture (Raspberry Pi running kernel 5.15.76-v8+, PHP 7.4.33) Most probably a PHP bug as

php -r "echo PHP_INT_SIZE;"
returns 4

Currently reverted to 2.24.3, as 2.24.4 fails completely.

Are you really using arm64 AND PHP 64bit?
Because when PHP_INT_SIZE = 4 it is 32bit.

The largest integer supported is 2147483647 in 32 bit and 9223372036854775807 in 64 bit.

32bit issues:

1. Just like the Maya calendar ended in 2012, the Unix Epoch ends in 2038
2. IMAP message UID's and UIDVALIDITY > 2147483647 will fail
3. IMAP Quota > 2GB (2147483647 / 1024 / 1024 / 1024) will fail
4. UID > 2147483647 then the messages list looks empty
5. etc.

So, if we allow 32bit, this does have complications.

Are you accidentally using 32b userland on a 64b kernel?

You can test with: $file $(which php)
It should say: /usr/bin/php: ELF 64-bit LSB pie executable

Just checked and apparently I really am running 32bit userland on 64bit kernel ... which came as quite a surprise to me ;) Thank you.
