You can use the response file feature (all DJGPP programs support it), 
like this:

	gcc -c foo.c @includes.list

Where the file `includes.list' names all the -I switches separated by 
whitespace (blanks or newlines).

This is all described in the FAQ, btw (section 16.4).

You can also set the environment variable C_INCLUDE_PATH to the list of 
the directories separated by semi-colons; then you don't need the -I 
switches at all.  (This environment variable is described in the GCC 
documentation, which see.)
