AC_CONFIG_HEADER(config.h:config.in)

dnl Provide the current PCRE version information. Do not use numbers
dnl with leading zeros for the minor version, as they end up in a C
dnl macro, and may be treated as octal constants. Stick to single
dnl digits for minor numbers less than 10. There are unlikely to be
dnl that many releases anyway.
