On  the m68k-motorola-sysv  I'm   running into trouble  with the  same
source file:  .../libstdc++/cinst.cc when compiling the complex stuff;
interestingly,     it looks  exactly  like  the   problems Marc  ESPIE
<19980129012327.03247@liafa1.liafa.jussieu.fr>       reported      for
egcs-980122 on m68k-unknown-netbsd:

I don't know if this problem  is related to my m88k  one, but, as they
occur in the  _same_  source  file and both  systems  use  COFF/sdb, I
actually guess it _is_ related.

Thanks to Marc's report  we now know, that  the change must  have been
incorporated before 980122!
