Description: If CFLAGS="-DMACRO_NAME=" is used in dm\bin\sc.ini; problems occur when the macro name length is 44-46, 50, or 51 characters.  Nope, I didn't test all cases of 1-1024 character lengths.  I just got, er, lucky with a macro name that caused me to look a tad further.

Expected results:  Using CFLAGS="-Dmacro=" should be the same as setting the
macro from the command line.
E.g. This command works fine:  dmc -v2
-DMACRO_NAME_THATS_44_CHARACTERS_XXXXXXXXXXXXX= test.cpp
See \dm\html\ctg\ctgLanguageImplementation.html#cpp_language, under the heading
"Internal Limits"
\dm\html\ctg\smake.html, under the heading "Defining Macros"
The above 2 docs are not _exactly_ concerning dmc.exe; but I'll make reference
to them none the less.

How to replicate:

1. In sc.ini, set CFLAGS="-DMACRO_NAME_THATS_44_CHARACTERS_XXXXXXXXXXXXX=" 2. dmc -v2 test.cpp

Apologia if this turns out to be user misunderstanding.
