[9fans] once is enough: VOID

[9fans] once is enough: VOID

[Brantley Coile]

I just spent 20 minutes figuring out what the above warning meant.
The line number given in the warning is incorrect, so it took the 20
minutes before I noticed that I had used the keyword `void' twice for
a function type a few lines below the last line of the previous
function, which was the line in the warning message.

Hope this saves someone else their 20 minutes.

One day I'll fix cc so it's diagnostics are more like those of cyntax.
A diagnostic should indicate the culprit, not where the parser
was when the semantic analysis was done.

Then again one day dumb-ass airline will show up with my luggage.

Consider yourself lucky.  I spent half a day trying to work out what
a gcc diagnostic meant and eventually cracked open a six pack
and wrote the entire file again from scratch - discarding the first
attempt.  Never did find out what the message meant.

My favorite error message of all time was `unintelligent control
statment was output with diagnostic.' That was on the batch job
control on an CDC 18/20 ITOS system.  It was years later that I
realized that my program had stopped without reading the last record
in the sysin and a data card was the next thing read by the batch
system.  I had put two sentinel numbers as input instead of one.  It
just couldn't figure out what to do with 99999 as a job control card.

The message should have been, `Hey stupid!  What's 99999 supposed to
mean?'
