 library. They are also documented in the
    --disable-cpp to the "configure" command. Otherwise, when "configure" is run,
    it will try to find a C++ compiler and C++ header files, and if it succeeds,
    it will try to build the C++ wrapper.
  . If you want to include support for just-in-time compiling, which can give
    large performance improvements on certain platforms, add --enable-jit to the
    "configure" command. This support is available only for certain hardware
    architectures. If you try to enable it on an unsupported architecture, there
    will be a compile time error.
  . When JIT support is enabled, pcregrep automatically makes use of it, unless
    you add --disable-pcregrep-jit to the "configure" command.
  . If you want to make use of the support for UTF-8 Unicode character strings in
    PCRE, you must add --enable-utf8 to the "configure" command. Without it, the

  Once "configure" has run, you can run "make". It builds two libraries, called
  libpcre and libpcreposix, a test program called pcretest, and the pcregrep
  command. If a C++ compiler was found on your system, and you did not disable it
  with --disable-cpp, "make" also builds the C++ wrapper library, which is called
  libpcrecpp, and some test programs called pcrecpp_unittest,
  pcre_scanner_unittest, and pcre_stringpiece_unittest. If you enabled JIT
  support with --enable-jit, a test program called pcre_jit_test is also built.
  The command "make check" runs all the appropriate tests. Details of the PCRE

  that tests the options of the pcregrep command. If the C++ wrapper library is
  built, three test programs called pcrecpp_unittest, pcre_scanner_unittest, and
  pcre_stringpiece_unittest are also built. When JIT support is enabled, another
  test program called pcre_jit_test is built.
  Both the scripts and all the program tests are run if you obey "make check" or

  --enable-utf8 was used. RunTest outputs a comment when it skips a test.
  Many of the tests that are not skipped are run up to three times. The second
  run forces pcre_study() to be called for all patterns except for a few in some
  tests that are marked "never study" (see the pcretest program for how this is
  done). If JIT support is available, the non-DFA tests are run a third time,
  this time with a forced pcre_study() with the PCRE_STUDY_JIT_COMPILE option.
  RunTest uses a file called testtry to hold the main output from pcretest

  The thirteenth test checks a number internals and non-Perl features concerned
  with Unicode property support.
  The fourteenth test is run only when JIT support is available, and the
  fifteenth test is run only when JIT support is not available. They test some
  JIT-specific features such as information output from pcretest about JIT
  compilation.
