*THE* Fortran compiler, *THE* C compiler???  OS/2 does not ship with any
compilers.  You have to purchase them from third party vendors.  Thus the
answer depends on which product you buy.  However, the two available
Fortran compilers both implement the ANSI standard, so they must have
support for double precision.

Don't know, but the compiler vendors often ship their own linker.  I know
that WATCOM's linker supports mixed language programming (Fortran and C).

Haven't used Xlib so I can't compare, but the OS/2 graphics "library" is
the set of GPI calls, of which there are a lot.
