The very first AC_CHECK for HEADERS found by autoconf does pull in the AC_REQUIRE(AC_PROG_EGREP) configure code. If we skip that configure part, which we do when threading was disabled, EGREP is unset for any subsequent check, breaking the checks for function prototypes at least. So we better do the AC_HEADER_STDC before any other AC_CHECK_HEADERS. --- configure.in | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
