[plt-scheme] mzc embedding question

Thank you for the reply, it is appreciated.
 
I ran the below, per your recommendation.  I found it only works if I also specify "--cgc".  So, the command-line I ran was:
"C:\Program Files\MzScheme\mzc.exe" --cgc --cc test_scheme_embed.c
 
yielding:mzc v371 [3m], Copyright (c) 2004-2007 PLT Scheme Inc."test_scheme_embed.c": [output to ".\test_scheme_embed.obj"]
 
followed by:
"C:\Program Files\MzScheme\mzc.exe" --ld test_scheme_embed.exe test_scheme_embed.obj
 
yielding:mzc v371 [3m], Copyright (c) 2004-2007 PLT Scheme Inc.mzc: not a MzScheme extension filename (doesn't end with .dll): test_scheme_embed.exe
 
I imagine there's something obvious I'm missing, but I haven't discovered what yet.  Any advice appreciated.
 
Thank you,
Matthew P.
