To solve the problem of undefined references in your dll, you need to
include the import library that containes GetModuleHandleA AT 4.  In this
case you need to include libkernel32.a since GetModuleHandle is in
kernel32.dll

Change you link command to...

#link DLL
ld --base-file tclvc.base --dll -o tcl76.dll \
regexp.o tclAppInit.o tclAsync.o tclBasic.o tclCkalloc.o \
tclClock.o tclCmdAH.o tclCmdIL.o tclCmdMZ.o tclDate.o tclEnv.o \
tclEvent.o tclExpr.o tclFCmd.o tclFHandle.o tclFileName.o tclGet.o \
tclHash.o tclHistory.o tclIO.o tclIOCmd.o tclIOSock.o tclIOUtil.o \
tclInterp.o tclLink.o tclLoad.o tclLoadNone.o tclMain.o  \
tclNotify.o tclParse.o tclPkg.o tclPosixStr.o tclPreserve.o tclProc.o \
tclUnixChan.o tclUnixFCmd.o tclUnixFile.o tclUnixInit.o tclUnixNotfy.o \
tclUnixPipe.o tclUnixSock.o tclUnixTime.o tclUtil.o tclVar.o panic.o  \
init.o fixup.o  $LIBPATH/libcygwin.a -e _dll_entry AT 12 \
$LIBPATH/libkernel32.a
