The /D compiler switch is used to define a constant value to the
preprocessor. It is equivalent to using a #define statement in the
source code. The C version 6.00 "Microsoft C Reference" manual gives
the syntax as follows:

   /Did[=[value]]

"Value" can be a number, character, or string constant such as "foo".
In order to define a string constant, the '\"' escape sequence must be
used. This requirement is undocumented. Please see the example shown
below, where FOO is defined as "bar":

   cl /DFOO=\"bar\" s.c
