Older perls misparse srand(()):

blead:/git_tree/perl$ perl -wle'print srand(())'
Use of uninitialized value in srand at -e line 1.
0 but true

Blead does things differently, but still not quite right, why the
uninitialized warning? and why the integer overflow warning?

blead:/git_tree/perl$ ./perl -wle'print srand(())'
Use of uninitialized value in srand at -e line 1.
Integer overflow in srand at -e line 1.
