  regexec: use pcre as our fallback/builtin regex Use PCRE 8.42 as the builtin regex implementation, using its POSIX compatibility layer. PCRE uses ASCII by default and the users locale will not influence its behavior, so its `regcomp` implementation is similar to `regcomp_l` with a C locale.

  /* This module contains global variables that are exported by the PCRE library.
  PCRE is thread-clean and doesn't use any global variables in the normal sense.
  However, it calls memory allocation and freeing functions via the four
  indirections below, and it can optionally do callouts, using the fifth
  indirection. These values can be changed by the caller, but are shared between
  all threads.
  
  For MS Visual Studio and Symbian OS, there are problems in initializing these
  variables to non-local functions. In these cases, therefore, an indirection via
  a local function is used.
  
  Also, when compiling for Virtual Pascal, things are done differently, and
  global variables are not used. */
