Help: gcc problem in Cygwin!

["Frank C." <francisspeech at yahoo dot com>]

Dear all,

I've been trying to install a software on Cygwin under
Windows XP, but without any success. The steps are (1)
'./configure', and (2) 'make'.

I had following error message after running 'make'.

cygpath: can't convert empty path
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../libcygwin.a(libcmain.o)
:: undefined reference to '_WinMain@16'
collect2: ld returned 1 exit status
make: *** [libquicknet3.a] Error 1


Can anyone let me know what's wrong here? It seems
that there is a confusion on which linker to use for
gcc, and GNU ld is not on the path. I attach the
output from './configure' at the end. Do you think it
is related to those outputs? If so, how to fix it? If
not, what's the cause?
checking for ld used by GCC... ${CXX}
checking if the linker (${CXX}) is GNU ld... no


Appreciate your help!

Best,
Frank
