For a long time I thought Csound environment variables like $INCDIR
were only able to contain one path.  When I finally looked at the code
I realized they do support multiple paths, but the paths must be
separated by semicolons.

Using semicolons for path separators in environment variables is a
Microsoft Windows convention.  Unix traditionally uses colons for this
purpose.

Maybe you will consider something like the following patch which sets
the default environment variable path separator to a colon, and only
uses a semicolon when WIN32 is defined.

I hope this would make the multiple path behavior more easily
discoverable for Unix users.

This patch was built and tested on Linux only, so definitely needs a
look on Windows and other platforms.

Cheers,

J

P.S. Currently in git include/sysdep.h is duplicated in its entirety
in...

    iOS/Csound iOS Examples/csound-iOS/headers/sysdep.h

This patch does not modify that copy of the file.
