### Summary

This is the final release of PCRE1. A few minor tidies are included.

1. CMakeLists.txt has two user-supplied patches applied, one to allow for the
setting of MODULE_PATH, and the other to support the generation of pcre-config
file and libpcre*.pc files.
2. There was a memory leak if a compile error occurred when there were more
than 20 named groups (Bugzilla #2613).
3. Fixed some typos in code and documentation.
4. Fixed a small (*MARK) bug in the interpreter (Bugzilla #2771).
