These versions came out about a year ago.  There have been
several new versions since, where things have changed; 
the code snip you quote cannot be found in the present 
version (3.55) of the file in exactly that form. 
Get the newest from ftp://ftp.maths.bath.ac.uk/pub/dream/

It looks like it should be defined in some system header file. 
Note that these statements in MidiOpen() are contained inside 
various #ifdefs, so you must make sure that you have the 
right ones for your compiler and platform (don't know which 
ones though, since I unfortunately don't do much of either 
Linux or MacCsound).

I'd like to see a file that collects the preprocessor flags 
for all the compiled versions available from Bath (and other
places).

Good luck,
