Bug using computed variable names together with call

[Onno Garms]

Hello,

I think I've found a bug in gnu make. My version of gnu make is a bit 
outdated so I cannot promise that the bug is still there or still not in 
the list of known bugs. But currently I definitely don't have the time to 
install a new version of gnu make.

The bug occurs when using computed variable names together with call. I 
expected gmake to echo "b" twice in the last command. However it echoed an 
empty string and "b".

Computed variable names like in test1 seem not to work together with call 
while the workarround in test2 works.

Short feedback would be appreciated.

Sincerely
Onno Garms
