Hi,

the following line create a BUG in autoconf
> # if 'CFLAGS' is NOT set, than macro 'AC_PROG_CC' set 'CFLAGS=-g -O2'
in seems that a M4-MACRO in COMMENT is a problem.

without this line… it works.

#       then increment AGE.
#
#    6. If any interfaces have been removed since the last public release,
#       then set AGE to 0.
#
#     *_Never_* try to set the interface numbers so that they correspond
#  to the release number of your package.  This is an abuse that only
#  fosters misunderstanding of the purpose of library versions. Instead,
#  use the `-release' flag (*note Release numbers::), but be warned that
#  every release of your package will not be binary compatible with any
#  other release.
