Nope - that's why we have #ifdef/#endif

Not on a modern CPU where changing the flow of control disrupts instruction
caching.

Well - I wouldn't count batch scripting as programming...But if you use a decent
batch scripting language like 'bash' under Linux (also works under Windows)
then it has all of the standard C flow control constructs and 'goto' is not
needed.

Yep - BASIC programming was probably the last time I used a GOTO.
Fortunately, even BASIC programmers now have VisualBasic which can
be programmed quite effectively without GOTO's.
