97    PCRE is written in C and is normally compiled as a C library. However, it is
98    possible to build it as a C++ library, though the provided building apparatus
99    does not have any features to support this.

272    Using HP's ANSI C++ compiler (aCC)
273    ----------------------------------
274    
275    Unless C++ support is disabled by specifiying the "--disable-cpp" option of the
276    "configure" script, you *must* include the "-AA" option in the CXXFLAGS
277    environment variable in order for the C++ components to compile correctly.
278    
279    Also, note that the aCC compiler on PA-RISC platforms may have a defect whereby
280    needed libraries fail to get included when specifying the "-AA" compiler
281    option. If you experience unresolved symbols when linking the C++ programs,
282    use the workaround of specifying the following environment variable prior to
283    running the "configure" script:
284    
285      CXXLDFLAGS="-lstd_v2 -lCsup_v2"
