# 2007-09-14 mod by Sheri so 7.4 supported configuration options can be entered
|
| 10 |
# 2007-09-19 Adjusted by PH to retain previous default settings
|
| 11 |
# 2007-12-26 (a) On UNIX, use names libpcre instead of just pcre
|
| 12 |
# (b) Ensure pcretest and pcregrep link with the local library,
|
| 13 |
# not a previously-installed one.
|
| 14 |
# (c) Add PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, and
|
| 15 |
# PCRE_SUPPORT_LIBBZ2.
