My MSVC++ 'demangle fu' is not up to that Those must be from

By not explicitly telling ld what to export, you are implicitly telling
it to export-all symbols from all your objects and archives, excluding a
few system libs. Tell ld to exclude tclstub84.lib from exports, as well
$ gcc -v -shared -mno-cygwin \
-o libTclMagick.dll \
-L'/cygdrive/c/Program Files/ImageMagick' \
TclMagick.o \
-ltclstub84 \
-lCORE_RL_wand_ -lCORE_RL_magick_ \
-Wl,--exclude-libs,tclstub84.lib
That did it. Thanks much.
Where can I learn about this "export" stuff? I've never, ever had to
"export" anything (via ld) when making a .so on unix -- it's all done
(for C) by *not* declaring a symbol as "static". Any suggestion on
a tutorial that explains the how and why when linking dll's on
windows?
I'd recommend going to the source for information on DLLs:
