500    #
501    #   - libbz2 uses the Pascal calling convention (WINAPI) for the functions
502    #     under Win32.
503    #   - The standard autoconf AC_CHECK_LIB fails to include "bzlib.h",
504    #     therefore missing the function definition.
505    #   - The compiler thus generates a "C" signature for the test function.
506    #   - The linker fails to find the "C" function.
507    #   - PCRE fails to configure if asked to do so against libbz2.
508    #
509    # Solution:
510    #
511    #   - Replace the AC_CHECK_LIB test with a custom test.
