Subject: B20: undefined reference to cygwin32_conv_to_path

This simple program compiles fine when using the "C" compiler.
 Works if it is named "tst.c" and gcc -o tst.exe tst.c.

Will not work if it named tst.cpp.
When I try to use the "C++" compiler I get "undefined reference
cygwin32_conv.......". I tried linking to the cygwin library.

g++ -o tst.exe tst.cpp -lcygwin

What library do I need to include? 
###############################################
#include <windows.h>
void cygwin32_conv_to_full_win32_path(const char *path, char
*win32_path);

int main()
{
static char arg[]="c/help/me";
char fn[40];
  cygwin32_conv_to_full_win32_path(arg, fn);
printf ("TEST=%s\n",fn);
}

#############################################
Outputs a valid Win32 path when compiled, nice!
Just downloaded the latest version B20. This stuff is very cool.
I need to use the path conversion function in C++ program I would like
to port to windows.
Thanks for any help
