glib2-upstream compilation failures on 10.5

Compilation with clang 6.0 fails with:

Undefined symbols for architecture x86_64:
  "_close$NOCANCEL$UNIX2003", referenced from:

gcc 7 has the same errors as clang 7

I don’t think that 64 bit libs have symbols that contain $UNIX2003 to link against…

you might be the only person trying to build 10.5 Intel 64 bit

Riccardo, let's track all of this via issue:67307, since it all relates to fixing builds for the glib2 ports.

Might be, most people stick to 32bit even if he CPU is 64bit capable or upgraded to 10.6. I have two twin machines. Does this mean that the 64bit libs are "poor" ? where should these symbols be (which library?)

I tried on the other 32bit and I get to the standard error:

I added

configure.cxxflags-append -std=c++11

but it still doesn't work.
