You must be kidding.  DJGPP comes with full sources to its C library.
Just download v2/djlsr201.zip, and look into the sources of `random'
(src/libc/compat/stdlib/random.c).

Btw, you should distinguish between the compiler and the library.
GCC knows nothing about the DJGPP C library.  To GCC, `random' is just
another function, it doesn't even know whether it is in the library or
written by you as part of your program.
