[Bug libgcj/38872] New: [4.4 Regression] libgcj.so dropped _Jv_CreateJavaVM and _Jv_GetStringChars symbols

["jakub at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

While comparing list of exported symbols, libgcj_bc.so.1 hasn't dropped any
symbols from 4.3 (correct, hasn't changed SONAME), but libgcj.so.10 dropped
_Jv_CreateJavaVM and _Jv_GetStringChars symbols compared to libgcj.so.9.
That wouldn't normally be an issue (they have different SONAME), but in this
case, as they are listed in libgcj_bc.so and thus part of libgcj_bc.so.1
ABI, this is an ABI break.  Seems _Jv_CreateJavaVM is still exported from
libgcj.so.10, but unlike 4.3 as extern "C++" name (mangled,
_Z16_Jv_CreateJavaVMP14_Jv_VMInitArgs), while previously
it was exported as extern "C".  _Jv_GetStringChars isn't exported at all.

Seen at least on x86_64-linux and i686-linux.

Can this be fixed before 4.4 release?
