#
# Note:
#
# If for any reason autoconf fails, run "autoreconf -i --install " and try again.
# This is how the error looks like on Arch Linux:
# ./configure: line 3064: syntax error near unexpected token `newline'
# ./configure: line 3064: `AX_CHECK_COMPILE_FLAG('
#
# We rely solely on autoconf, without automake. Apparently, in this case
# the macros from m4 directory are not picked up by default by automake.
# "autoreconf -i --install" seems to fix the problem.
