Alias and if

[XIAO Gang]

Version: GNU bash, version 3.00.16(1)-release (i386-pc-linux-gnu)

Hardware: AMD Athlon 3GHz+, 1G RAM.

OS: Linux (Knoppix-3.9).

Compilation: Distributed by Debian.

Description: An alias defined within an "if" branch has no effect.

Recipe: in the following script, the alias "mycp" is unknown command. 
The problem disappears when
the line "alias myls=ls" is moved before the "if" line.

Note that the definition is however recorgnized by "alias -p".

The same phenomenon is reported on slightly different recent builds of 
Linux.
