            Bug ID: 89750
           Summary: Missing line continuation in definition of MAYBE_WARN
                    in configure
           Product: cairo
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Mac OS X (All)
            Status: NEW
          Severity: minor
          Priority: medium
         Component: general
          Assignee: chris at chris-wilson.co.uk
          Reporter: baker at usgs.gov
        QA Contact: cairo-bugs at cairographics.org

There is an unintentional (benign) missing line continuation "\" in the
definition of MAYBE_WARN in configure.  configure completes and issues a
WARNING:

configure: WARNING: cache variable cairo_cv_warn_maybe contains a newline

The error is at line 18461 in configure (release 1.14.2):

$ grep -w -n '[-]Wpacked' configure
18461:-Wpointer-arith -Wwrite-strings -Wsign-compare -Wpacked

I fixed it with sed:

$ sed -i -e '/^MAYBE_WARN=/,/^MAYBE_C_SPECIFIC_WARN=/s/-Wpacked$/-Wpacked \\/'
configure

$ grep -w -n '[-]Wpacked' configure
18461:-Wpointer-arith -Wwrite-strings -Wsign-compare -Wpacked \
