If by ``integrate'' you mean to make library functions support long
file names automatically (on plain DOS), then IMHO this is a Bad Idea.
Accessing long file names on plain DOS requires to read large portions
of disk structure into memory to access the LFN entries.  This would
tremendously slow down the program and bloat the code of every DJGPP
image.

I think this kind of task is best handled in a separate library, which
people could link in if they need.  For example, you could overload
the standard definition of __dpmi_int, which serves to issue all DOS
(and BIOS) interrupts.
