           Summary: Don't create empty file if gperf fails
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: rafael.espindola at gmail.com


Currently makeprop.pl, makevalues.pl and make-hash-tools.pl run gperf with:

system("gperf .... > $file") == || die ...

This creates an empty $file if gperf fails, which doesn't play very well with most build systems. This patch changes them to use

system("gperf .... --output-file=$file")
