[Bug fortran/21950] New: All gfortran execution tests fail on Tru64 UNIX V4.0F: scalbn unresolved

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Even with the patch to fix PR libfortran/15234

	http://gcc.gnu.org/ml/fortran/2005-06/msg00118.html

(and already mentioned there), all gfortran execution tests fail on
alpha-dec-osf4.0f like this:

% LD_LIBRARY_PATH=../../alpha-dec-osf4.0f/libgfortran/.libs:.. ./PR19754_2.exe
4552:./PR19754_2.exe: /sbin/loader: Error: Unresolved symbol in ../../alpha-dec-osf4.0f/libgfortran/.libs/libgfortran.so.0: scalbn
4552:./PR19754_2.exe: /sbin/loader: Fatal Error: this executable has unresolvable symbols

The platform has no definition of scalbn whatsoever.

Environment:
System: OSF1 rimsky V4.0 1229 alpha
Machine: alpha
	
host: alpha-dec-osf4.0f
build: alpha-dec-osf4.0f
target: alpha-dec-osf4.0f
configured with: /vol/gnu/src/gcc/gcc-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --host alpha-dec-osf4.0f --build alpha-dec-osf4.0f --target alpha-dec-osf4.0f --with-gmp-dir=/vol/gnu/obj/gmp-4.1.3 --with-mpfr-dir=/vol/gnu/obj/gmp-4.1.3 --enable-languages=c,c++,f95,java,objc --disable-libmudflap

How-To-Repeat:
Bootstrap and test mainline (or the 4.0 branch) on alpha-dec-osf4.0f with
the patch above applied.
------- Additional Comments From ro at techfak dot uni-bielefeld dot de  2005-06-07 16:21 -------
Fix:
Provide a scalbn replacement.  E.g. there is one in libjava
(java/lang/s_scalbn.c).
