 The Cygwin is famous about changing every month, so expecting the symbol names being
the same after one year is quite optimistic... I can be wrong, but the '__imp__<name>'
were changed into '___imp__<name>' when changing from b20 to 1.0 --- or vice versa...

 Just check with 'nm' what the symbol names are now in 'libcygwin.a' or 'libc.a', whatever
the C-library in Cygwin was. And then edit them into your sources, 'tcl/win/tclEnv.c'
here... (There are quite a lot more...).

 A better approach could be to check the newer Hitachi-release or use newer sources
and update one piece at a time: binutils, GCC and Insight, using the latest releases
and patches for H8/300... Ok, I heard about the new Hitachi release from a 'bug report'
after giving the site address for the '99r1p1' :

 The Cygwin-1.1.1 was installed in the 'reporter's machine earlier, so this sounded
to be the famous UTNC error ("Update The Nice Cygwin1.dll"). But other experiences
about the new 'official Hitachi-distribution' could prove this...

 The '99r1p1' is very old and I couldn't see any sanity in trying to get a production
compiler from it, gcc-2.95.2 and the Kazu Hirata's patches would suit for a new toolset
much better:

Hi, 
I just released new RPMs for h8300-hms-gcc-2.95.2. 

        http://www.hdl.co.jp/~kban/h8300-hms/ 

If you just want to take the patch, 

        http://www.hdl.co.jp/~kban/h8300-hms/h8300-hms-gcc-2.95.2-6.patch 

Until gcc-3.0 comes out, I might make gcc-2.97 RPMs just for experimental
purposes.  For productions, please use h8300-hms-gcc-2.95.2.

2.97 is currently broken in the following areas: 

libgcc2 compilation 
floating point emulation 

Both have workarounds, but there is no real solution yet. 

Thanks, 

Kazu Hirata

 I would expect the Kazu's patches installing upon the current Cygwin
gcc-2.95.2-x sources, but who knows...

Cheers, Kai
