-This is a default version of the tables that assumes ASCII encoding. A program
-called dftables (which is distributed with PCRE) can be used to build
-alternative versions of this file. This is necessary if you are running in an
-EBCDIC environment, or if you want to default to a different encoding, for

-The following #includes are present because without them gcc 4.x may remove the
-array definition from the final binary if PCRE is built into a static library
-and dead code stripping is activated. This leads to link errors. Pulling in the
