#63530: libhandy @1.2.0_0: Compiler mismatch invoking g-ir-scanner

     Type:  defect      |     Status:  assigned
 Priority:  Normal      |  Milestone:

------------------------+--------------------------------------------
 I'm working through some issues compiling libhandy. When I enforce C11
 with {{{compiler.c_standard=2011}}}, MacPorts selects {{{gcc-mp-7}}} for
 the main compilation, but then {{{g-ir-scanner}}} apparently selects
 {{{gcc-apple-4.2}}} during the build, so I error out with some
 unrecognized flag warnings.

 }}}

 I'm not sure where the bug lies exactly, but {{{g-ir-scanner}}} should be
 invoking the same compiler as the main build. The unrecognized flags
 appear to originate with libhandy.

 Full log to follow.
