 Following a report on the mailing list (gnuplot doesn't compile on Mac OS
 X 10.6 with Xcode 4.2 which doesn't have C99-compliant compiler) here's a
 patch that should solve the problem for that platform (and I hope that it
 will be applied upstream).

 If anyone else was bitten by this, please report.

 Disclaimer: I'm not able to test this patch since I don't have access to
 old Xcode on 10.6.
