Hello Pavel and Ali!
Why did you comment out AC_CONFIG_AUX_DIR? If it doesn't work, then I'll rather wait until it's fixed.
po/Makefile from gettext 0.11.x assumes consfig.status is in AC_CONFIG_AUX_DIR, so there 3 ways to fix this:
1) Fix gettext developers ;-) 2) Patch po/Makefile from configure 3) Remove AC_CONFIG_AUX_DIR.BTW, there is no needs for potfiles command in configure.in, at least on Slackware with gettext 0.10.40 and on RedHat 7.3+gettext 0.11.1.
