The 1 comes likely from -Dfoo being equivalent to Dfoo=1 if there is no = on
the command line, and as the preprocessor internally doesn't use = signs but
spaces after macro name, we append " 1". -D"foo bar" is thus expanded as
-D"foo bar 1". "processed correctly" means what exactly?  You can't define
macro blabla(x, y) bleble[x,y], C doesn't have macros with spaces in the names.
 Garbage in garbage out in my eyes.
