exporting c++ special symbols

[Miroslaw Dobrzanski-Neumann]

Hi,

When using -export-symbols-regex option libtool filters out following symbols
before they have a chance to pass use defined filter

* for gcc 2.x
  symbols that start with '_.' which are c++ destructors
  $ c++filt _._2xx
  xx::~xx(void)

* for gcc 3.x
  symbols that are flagged vith 'V' which are c++ type infos and virtual tables
  $ nm xx.o
    00000020 T _ZN2xxC1Ev
    00000000 T _ZN2xxC2Ev
    000000c0 T _ZN2xxD0Ev
    00000080 T _ZN2xxD1Ev
    00000040 T _ZN2xxD2Ev
    00000000 V _ZTI2xx
    00000000 V _ZTS2xx
    00000000 V _ZTV2xx
             U _ZTVN10__cxxabiv117__class_type_infoE
             U _ZdlPv
  $ nm xx.o | c++filt
    00000020 T xx::xx[in-charge]()
    00000000 T xx::xx[not-in-charge]()
    000000c0 T xx::~xx [in-charge deleting]()
    00000080 T xx::~xx [in-charge]()
    00000040 T xx::~xx [not-in-charge]()
    00000000 V typeinfo for xx
    00000000 V typeinfo name for xx
    00000000 V vtable for xx
             U vtable for __cxxabiv1::__class_type_info
             U operator delete(void*)
    
with this there is not way to export only a given class because either a 
destructor is missing (gcc 2.x) or rtti information is missing (gcc 3.x)

Could you fix this bug?
