# OBSOLETE MACRO
#
# This macro has been deprecated because of technical flaws, i.e. it may
# generate false positive results. Further details can be found at
# <http://savannah.nongnu.org/patch/?6848>.
#
# SYNOPSIS
#
# AX_C_PRINTF_THSEP
#
# DESCRIPTION
#
# This macro checks whether the compiler supports the ' flag in printf,
# which causes the non-fractional digits to be separated using a separator
# and grouping determined by the locale. If true, HAVE_PRINTF_THSEP is
# defined in config.h
