Reproduced. This seems to be a bug in the development version which unfortunately has crept into rawhide. Perhaps I will revert it to the 2.52 release.
On second thoughts. Your example is a case of "underquoting". The macro calls need to be quoted properly for safe expansion (see "Autoconf Language" in the autoconf manual). eg like this: AC_CHECK_LIB(z, gzsetparams, [AC_CHECK_HEADER(zlib.h,,[AC_MSG_ERROR(zlib headers not found)])], [AC_MSG_ERROR(zlib library not found)]) The fact that this worked under 2.52 and 2.13 was just pure luck and should not be relied on.
