[parted-devel] [PATCH 1/3] configure.ac: Check ABI against ABI version 2

[Shin'ichiro Kawasaki]

GCC 8 fails to compile libparted/labels/aix.c with an error:

  CC       aix.lo
cc1: error: -Wabi won't warn about anything [-Werror=abi]
cc1: note: -Wabi warns about differences from the most up-to-date ABI, which is
also used by default
cc1: note: use e.g. -Wabi=11 to warn about changes from GCC 7
cc1: all warnings being treated as errors
make[4]: *** [Makefile:1250: aix.lo] Error 1

To avoid the build failure, specify ABI version 2 to check ABI change
from GCC 4.9.
