error compiling stl samples with g++ in cygwin

[TheOne]

I downloaded sample codes from http://www.cs.rpi.edu/~musser/stl-book/source/src.zip
and tried to compile them.

I started my cygwin on xp, renamed Makefile.unix to Makefile and typed
"make". After several successful compilation, it spat out following
error :

/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../libcygwin.a(libcmain.o):
(.text+0xab): undefined reference to `_WinMain@16'
collect2: ld returned 1 exit status
make: *** [ex04-01] ¿À·ù 1

There's no WinMain in the code. Strangely, when I retried "make",
compile is succuessful for the file but again after several succuess,
make complain with the same error message with another source code.

What can cause the problem?

TIA.

Wrong group. Try gnu.g++.help.

F/U set.
