From these comments and the Readme of Tcl8.4a2/win directory which follows,
I have tried to build Tcl8.4a2 again.

It seems to me that Cygwin can build Tcl8.4a2.
However, I get the same error message.
>tclWin32Dll.c:348: `__try' undeclared (first use in this function)
>tclWin32Dll.c:348: (Each undeclared identifier is reported only once

etc.

My configure methods are:
1)
% cd /usr/local/src/Tcl8.4a2/win
% ./configure --enable-gcc --enable-shared
2)
% CC='gcc -mno-cygwin' ./configure --enable-gcc --enable-shared
3)
% cd /usr/local/src/Tcl8.4a2/unix  :::(not win)
% CC='gcc -mno-win32' ./configure --enable-gcc --enable-shared

All get error messages.
