This does not fix the issue. You're casting, but the value does not fit
in 32 bit and the warning still remains.
I am afraid that 32 bit for gd->ram_size are not enough anymore...
We can fix the warning setting maybe a lower amout of memory (I am
expecting that now the value is truncated and a wrong output is shown on
the console), but for the future gd->ram_size should move to 64 bit.
Best regards,
Stefano
