In the following code, __gfortran_os_error is thrown as unresolved at link
time. The trouble goes away if
//'=0'
is removed.
$ cat silly.f
character(16) :: str,namx
len=4
namx='abcdefg'
str=' '
str(7:)=namx(1:len)//'=0'
write (6,*) str
end
$ gfortran silly.f
/usr/bin/ld: Undefined symbols:
__gfortran_os_error
collect2: ld returned 1 exit status
$ gfortran -v

Works OK for me on x86-64-gnu-linux. My system is a 5/27/2007 bootstrap of 4.3
trunk.
This could be platform specific. Can another Darwin user confirm this. Looks
like the problem may be platform specific. You could perhaps try a later snap
shot. (Yes I know, that only been a few days)

Is that a compiler you built from scratch, or did you build it, update the
source and rebuilt it not-from-scratch? That's a case where I'd expect to see
that kind of error. Otherwise, I don't know how this is happening.

The compiler was downloaded from the link in http://hpc.sourceforge.net/ .

Hard to tell what is going wrong. I've been building and using compilers on
i386-darwin with no problem. Please contact the people behind HPC MacOS X to
see if they can help you using this compiler, or download our own
(http://gcc.gnu.org/wiki/GFortranBinaries#MacOS)
If you find indication that the bug is indeed with GCC itself, or can reproduce
it on your system using a freshly built compiler, please reopen this PR or file
a new one.
