[Mingw-users] entry points for DLLs missing

Hello,
I try to build libxml-2.5.11 with MinGW and cygwin,
using the autoconfiscated build. The linking process
fails due to an "undefined reference to `WinMain@16'",
the output of make can be found at the end of this
mail.
I would greatly appreciate any hints!
thanks,
Bernhard
I use:
libtool-1.5
gcc-3.2.3
autoconf-2.57
configure is invoked with:
export CC='gcc -mcpu=pentium -march=pentium -mmmx -msse -msse2
-mfpmath=sse -mthreads -mno-cygwin -mms-bitfields'
export CPPFLAGS='-Ic:/MinGW/include -Ic:/gtk_tml/include'
export LDFLAGS='-no-undefined -Lc:/MinGW/lib -Lc:/gtk_tml/lib'
./configure --with-ftp=no --with-http=no --enable-shared --disable-static
--prefix=c:/gtk_tml --host=i386-pc-mingw32 --target=i386-pc-mingw32
--enable-debug=yes
output of make:
[...]
