+Due to inlining match() by recent GCC, the stack estimator reported 4-bytes
+stack consumption.

+%description
+The PCRE library is a set of functions that implement regular expression
+pattern matching using the same syntax and semantics as Perl 5. PCRE has
+its own native API, as well as a set of wrapper functions that correspond
+to the POSIX regular expression API. The PCRE library is free, even for
+building proprietary software.
+
+PCRE was originally written for the Exim MTA, but is now used by many
+high-profile open source projects, including Apache, PHP, KDE, Postfix,
+and Nmap. PCRE has also found its way into some well known commercial
+products, like Apple Safari. Some other interesting projects using PCRE
+include Chicken, Ferite, Onyx, Hypermail, Leafnode, Askemos, Wenlin, and
+8th.
