DJGPP doesn't have the rand48 family of functions in its C library.
Seems like that part of STL assumes that it does.

You can work around by writing a trivial wrapper around `rand' or
`random'.

It should probably be reported as a bug to the STL maintainers.  Or
maybe the procedure that built libstdcxx.a for DJGPP has some bug
whereby it didn't pay attention to the fact that there's no lrand48.
You will have to look at the sources to know for sure.
