/* NOTES FOR FUTURE MAINTAINERS: Do not use numbers with leading zeros, because
|

|
they may be treated as octal constants. The PCRE_PRERELEASE feature is for
|
||
|
|
identifying release candidates. It might be defined as -RC2, for example. In
|
||
|
|
real releases, it should be defined empty. Do not change the alignment of these
|
||
|
|
statments. The code in ./configure greps out the version numbers by using "cut"
|
||
|
|
to get values from column 29 onwards. These are substituted into pcre-config
|
||
|
|
and libpcre.pc. The values are not put into configure.ac and substituted here
|
||
|
|
(which would simplify this issue) because that makes life harder for those who
|
||
|
|
cannot run ./configure. As it now stands, this file need not be edited in that
