Why on earth does it show the error on line 6 on powerpc?!

No idea, sorry. Is that the problem? Supposed to be an error but on a
different line?

Yes. On line 5, see the dg-error marker.

The interesting thing is that for a x86_64 -> aarch64-linux cross the error
_also_ appears on line 5:
> ./f951 -quiet /home/rguenther/src/gcc3/gcc/testsuite/gfortran.dg/pr95690.f90 -o pr95690.s -fno-diagnostics-show-caret
/home/rguenther/src/gcc3/gcc/testsuite/gfortran.dg/pr95690.f90:5:0: Error:
initializer for floating value is not a floating constant
so - what line number does the test report for a aarch64 -> x86_64-linux cross?
Note the error is emitted via output_constant via
4980 case REAL_TYPE:
4981 if (TREE_CODE (exp) != REAL_CST)
4982 error ("initializer for floating value is not a floating
constant");
so it depends on input_location (ick). Now the question is where on earth
input_location has a dependence on the host ...
On x86_64 the respective location is set via
New value = 2147483652
expand_gimple_stmt (stmt=<gimple_call 0x7ffff69dd260>)
at /home/rguenther/src/gcc3/gcc/cfgexpand.c:3847
3847 expand_gimple_stmt_1 (stmt);
(gdb) l
3842 it would be better if the diagnostic routines used the source
location
3843 embedded in the tree nodes rather than globals. */
3844 if (gimple_has_location (stmt))
3845 input_location = gimple_location (stmt);
3846
3847 expand_gimple_stmt_1 (stmt);
(gdb) p debug_gimple_stmt (stmt)
# .MEM_7 = VDEF <.MEM_6>
_gfortran_transfer_real_write (&dt_parm.0, &C.3905, 4);
which is where we expand C.3905 from.

David "fixed" this on trunk with the following, the testcase still fails on the
branch and of course we don't know why it exhibits this particular behavior.

testsuite: Adjust gfortran.dg/pr95690.f90 line number.
gfortran produces associates a different line number for the same error
message depending on x86 versus other architectures. This patch adjusts
the dg-error line number depending on the target.

This change broke the test on sparc-sun-solaris2.11 (both 32 and 64-bit):
+FAIL: gfortran.dg/pr95690.f90 -O (test for errors, line 6)
+FAIL: gfortran.dg/pr95690.f90 -O (test for excess errors)
Excess errors:

I added Solaris to the list of targets that see the error on line 5. Add it
wherever your target sees it.

This has almost certainly nothing to do with Solaris per se, but just
piles hack upon hack without trying to understand why the test FAILs on
some targets, but not on others.
So far, we have failure reports for at least
powerpc64le-unknown-linux-gnu, armv8l-unknown-linux-gnueabihf,
s390x-ibm-linux-gnu, aarch64-unknown-linux-gnu, arm-none-linux-gnueabi,
powerpc-ibm-aix7.2.0.0, ia64-suse-linux-gnu, m68k-unknown-linux-gnu.
This needs to be analyzed, not hacked around. Besides, the patch is
supposed to be posted to gcc-patches.
