MAINLD and SHLIBLD

I would like to always use ${CC} for linking the main binary and the
shlibs.

Inspection of configure.in reveals that we currently deviate in the
following cases:

			mainld				shlibld
	aix[2-9]*	ld				ld
	alpha*osf*	${FC} -g -nofor_main -fpe3	${FC}

I'm only speaking for alpha*osf*:

I think these settings have their roots in very old R versions, where we
had no means to determine the system dependent Fortran libraries (-lUfor
-lots ... for DEC compilers). Now it works without these settings, i.e. 
with mainld=shlibld=${CC}. 

With DEC compilers it still fails in a "make check" with 
  ../../bin/R --vanilla < base-Ex.R > base-Ex.Rout
  /bin/sh: 19080 Memory fault
but this is unrelated to shlibld and mainld settings, as it occurs the
same way with current settings. 

The combination gcc/g77 (version 2.95.2) works as before (successfull
"make check"), the nofor_main and fpe3 options where meaningless (and even
generated some warnings) for GNU compilers.

Here is what I did:  
agebhard@delta[R-1.2.0]$ diff configure.in.bak configure.in
630,633c630,635
<     mainld="${FC} -g -nofor_main -fpe3 "
<     cpicflags=
<     cxxpicflags=
<     shlibld=${FC}
---

    if test "${GCC}" != yes; then
  #    mainld="${FC} -g -nofor_main -fpe3 "
      cpicflags=
      cxxpicflags=
  #    shlibld=${FC}
    fi

DEC compilers have no PIC flags, thats the reason for setting them to "", 
but may be configure would guess this automatically.

This was with a current r-devel version, on alpha-dec-osf4.0e

	hpux*		${CC}				ld

Does anyone recall why we do not use ${CC} in these cases?  Did anyone
successfully build R on these platforms with ${CC} for mainld/shlibld?
(Inspection of ltconfig from libtool seems to indicate that ${CC} should
be possible ...)
