577503 - AIX configuration error in js/ctypes/libffi/configure script

Status: RESOLVED DUPLICATE of bug 545634

(Core :: js-ctypes, defect)

Description

[Uli Link (:ul-mcamafia)]

When the configure is run it hangs due to invalid compiler flag.
The compiler frontend then spawns the compiler help through the pager.
You have to manually press enter until the end of the compiler help.

Seems the error happens in/after line 23336 in js/ctypes/libffi/configure:

ac_try='${CC-cc} -Werror -S conftest.c -o conftest.s 1>&5'

Those flags are invalid for IBM XLC/C++ compiler.
IBM XLC/C++ and the ld does not have a visibility attribute, so this check should be skipped for AIX, setting the feature to unsupported. Don't see a "configure.in" here.
