The FAQ *does* mention this keyword in section 18.9.  It is not explained
anywhere else in the docs because DJGPP doesn't recognize this keyword. 
Its meaning is explained in the docs of the other DOS compilers that
support this keyword.  Generally it tells the compiler to generate special
code at entry and exit to the functions declared with this attribute; 
this code is required by the way hardware interrupts work on MS-DOS.  See 
the above section of the FAQ for the explanation of how to do the same 
with DJGPP.
