[fpc-pascal]SetSocketOptions() in Linux

[Brad Campbell]

G'day all,

This has been a problem for me for a couple of years and I have only
just solved it. (It was not a high priority).

S is a Socket.
I wanted to 
SetSocketOptions(S,SOL_SOCKET,SO_REUSEADDR,1,Sizeof(1));

I looked at heaps of C source, and they did it with an int
variable. So I used

Var
	Temp : Integer;

Temp := 1;
SetSocketOptions(S,SOL_SOCKET,SO_REUSEADDR,Temp,Sizeof(Temp));

This never worked, but it turns out that

Const
	Temp = 1;
SetSocketOptions(S,SOL_SOCKET,SO_REUSEADDR,Temp,Sizeof(Temp));

Or 

SetSocketOptions(S,SOL_SOCKET,SO_REUSEADDR,1,Sizeof(1));

Both work fine.
Why does the first one fail and both the second ones work.
What am I missing.

I have solved the problem and I'm much happier for it, but I'd like
to know what basic concept I'm not grasping.
