Annotation of embedaddon/pcre/configure.ac, revision 1.1.1.5
1.1 misho 1: dnl Process this file with autoconf to produce a configure script.
2:
3: dnl NOTE FOR MAINTAINERS: Do not use minor version numbers 08 or 09 because
4: dnl the leading zeros may cause them to be treated as invalid octal constants
5: dnl if a PCRE user writes code that uses PCRE_MINOR as a number. There is now
6: dnl a check further down that throws an error if 08 or 09 are used.
7:
8: dnl The PCRE_PRERELEASE feature is for identifying release candidates. It might
9: dnl be defined as -RC2, for example. For real releases, it should be empty.
