Hi, 
I've posted this message previously with no response.  Is this a legitimate
question (I'm kinda new at this)? 

I am trying to compile the example to build a relocatable DLL from the
http://sourceware.cygnus.com/cygwin/building-reloc-dlls.txt.  However, I am
using g++ instead of gcc, and I've converted foo2.c to a C++ class foo2.cc.
However, the reference to new in foo.c 
 foo2 f2 = new foo2(); 
is not resolvable and produces the following link error. 
ld -L
c:/cygnus/cygwin-b20/H-i586-cygwin32/lib/gcc-lib/i586-cygwin32/egcs-2.91.57
-lgcc -lstdc++ --base-file fooB.base --dll -o fooB.dll foo.o foo2.o init.o
fixup.o c:/cygnus/cygwin-b20/H-i586-cygwin32/i586-cygwin32/lib/libcygwin.a
-e _dll_entry AT 12 
foo.o(.text+0x25):foo.cc: undefined reference to `__builtin_new' 

I've tried moving the call to 'new foo2()' directly to the foo2.cc file,
with no help (I thought maybe you just couldn't call 'new' from a method
declared 'extern C'). 
Also, foo.o is not even generated from a file called foo.cc 
(the file is actually foo.c).  I suppose maybe g++ assumes the source file
to have a .cc extension, I'm not sure. 
Any advice greatly appreciated. 

Thanks! 
-Sonny
