True, it accept strings and negative decimal numbers and hexadecimal
numbers and even gives me identical binaries...

So you would say that the only valid parameter to -frandom-seed is an
unsigned decimal number?

-frandom-seed=18464 // correct
-frandom-seed=a48cb9 //wrong
-frandom-seed=foobar //wrong

Stephan
