y:

I just ran bootstraps on both sparc-sun-solaris2.11 and
i386-pc-solaris2.11.  x86 results are unchanged, but sparc is completely
miserable:

                =3D=3D=3D gfortran Summary for unix =3D=3D=3D

# of expected passes            18878
# of unexpected failures        16537
# of expected failures          177
# of untested testcases         1752
# of unresolved testcases       14688
# of unsupported tests          706

likewise with -m64.

Most (all?) tests fail to link now, failing to find one or more of

cabsq
copysignq
fmodq
roundq
sqrtq
truncq

e.g.

FAIL: gfortran.dg/coarray/alloc_comp_1.f90 -fcoarray=3Dsingle  -O2   (test =
for
excess errors)
Excess errors:
