AC_USE_SYSTEM_EXTENSIONS macro and to test for functions used by the JIT
modules.
52. Minor fixed to pcre2grep from Jason Hood:
* fixes some spacing;
* Windows doesn't usually use single quotes, so I've added a define
to use appropriate quotes [in an example];
* LC_ALL was displayed as "LCC_ALL";
* numbers 11, 12 & 13 should end in "th".
* use double quotes in usage message
