4.2 C++ test suite build problem on Solaris 10/SPARC

[Albert Chin]

While building gmp-4.2 on Solaris 10/SPARC:
  $ CC -V
CC: Sun C++ 5.7 Patch 117830-06 2006/02/13
  $ gtar jxf gmp-4.2.tar.bz2
  $ cd gmp-4.2
  $ ./configure CC=cc CFLAGS="-xO2" CXX=CC CXXFLAGS="-xO2" \
M4=/opt/TWWfsw/m4/bin/gm4 ABI=32 --enable-shared --enable-static \
--disable-dependency-tracking --enable-cxx
  $ gmake
  $ gmake check
  ...
gmake[4]: Entering directory `/opt/build/china/gmp-4.2/tests/cxx'
CC -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../../tests    -xO2 -c -o
t-assign.o t-assign.cc
"../../gmpxx.h", line 1389: Error: Formal argument 3 of type extern
"C" void(*)(void*,unsigned)* in call to
__gmp_get_memory_functions(extern "C" void*(*)(unsigned)*, extern "C"
void*(*)(void*,unsigned,unsigned)*, extern "C"
void(*)(void*,unsigned)*) is being passed void(*)(void*,unsigned)*.
"../../gmpxx.h", line 1390: Warning: The variable freefunc has not yet
been assigned a value.
1 Error(s) and 1 Warning(s) detected.
gmake[4]: *** [t-assign.o] Error 1

Anyone have a solution to this? I don't see what's wrong. I tried the
following small test program but it compiles ok:
  $ cat test.cc
#include <stdlib.h>

void __gmp_get_memory_functions (
  void * ( ** ) ( size_t ),
  void * ( ** ) ( void *, size_t, size_t ),
  void ( ** ) ( void *, size_t )
); 

struct __gmp_alloc_cstring { 
  char * str ; 
  __gmp_alloc_cstring ( char * s ) { str = s ; } 
  ~ __gmp_alloc_cstring ( ) { 
    void ( * freefunc ) ( void * , size_t ) ; 
    __gmp_get_memory_functions ( 0 , 0 , & freefunc ) ; 
    ( * freefunc ) ( str , 1 ) ; 
  } 
};
