786	config step auto::gettext throws warnings on Darwin/PPC	jkeenan	jkeenan	"This ticket concerns warnings generated during ''Configure.pl'' during config step ''auto::gettext'' on Darwin/PPC.  These warnings were initially observed in the ''io_cleanups'' branch, but in fact were present in trunk from before the point at which that branch was created.

''auto::gettext'' conducts an automated probe of your system to determine ''... whether the platform supports gettext. This is needed for Parrot internationalization.  They are  a set of tools that provides a framework to help other GNU packages produce multi-lingual messages.''

''auto::gettext'' composes a short C program on the fly and then executes that program.  The name of that program is ''test_xxxxx.c'', where xxxxx is a 5-digit number probably derived from a process ID.   The configstep compiles this program into an object file ''test_xxxxx.o'' and then into an executable ''test_xxxxx''.

You can diagnose warnings which occur during a particular configuration step by (a) running configuration with that step in verbose mode:
{{{
perl Configure.pl --verbose-step=auto::gettext
}}}  
and (b) in ''lib/Parrot/Configure/Step/List.pm'', temporarily deleting all configuration steps '''after''' the step you need to examine.  This helps to ensure that any files resulting from the execution of ''test_xxxxx'' are still present and have not been cleaned up by Configure.pl.  (No guarantees on the latter, though.)

Here's what I got when following the above steps on Darwin/PPC:
