I appear to be getting a similar error in cygwin:

g++ -c  -I. -I.. -I../liboctave -I../src -I../libcruft/misc  -DHAVE_CONFIG_H 
-mieee-fp -Wall -W -Wshadow -Wold-style-cast -g -O2 dynamic-ld.cc -o 
dynamic-ld.o
dynamic-ld.cc: In member function `bool octave_dynamic_loader::do_load(const
   std::string&, const std::string&)':
dynamic-ld.cc:268: error: ISO C++ forbids casting between pointer-to-function
   and pointer-to-object
