Subject: [PATCH] mcstrans: avoid missing prototypes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Mark local functions static.
Export functions of mcscolor.c in mcscolor.h and avoid bare extern
function declarations.
Drop unused function emit_whitespace().

Subject: [PATCH] mcstrans: port to new PCRE2 from end-of-life PCRE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Quoting pcre.org:
There are two major versions of the PCRE library. The current
version, PCRE2, released in 2015, is now at version 10.39.
The older, but still widely deployed PCRE library, originally
released in 1997, is at version 8.45. This version of PCRE is now at
end of life, and is no longer being actively maintained. Version
8.45 is expected to be the final release of the older PCRE library,
and new projects should use PCRE2 instead.
