Subject: dreal() and cdexp() missing from F77 compiler
Index:	usr.bin/f77/intr.c 2.11BSD

Description:
	The builtin functions dreal() and cdexp() show up as undefined
	when compiling a F77 program imported from 4.3BSD.

Repeat-By:
	Compile the test program below and observe the undefined 
	errors reported by the linker.

      complex*16 sum,term
      real*8 sigmar
c
      term = cdexp(sum)
      sigmar = dreal(sum)
      end

Fix:
	Apply the following patch to the Fortran compiler.  The capability
	to generate the conversions was already present in the compiler,
	only the table entries were missing for the two builtin functions.
