I'm sure this has been answered so sorry for the possible repetition.
I am trying to build the 2.8 version of gdb (came with emacs 18.52) on
a Sun 3 running SunOS 4.0. There seems to be a problem with a structure
definition. Gcc nicely reports:

core.c: In function core_file_command:
core.c:207: structure has no member named `c_fpstatus'
core.c:209: structure has no member named `c_fpstatus'
core.c:210: structure has no member named `c_fpstatus'
core.c:212: structure has no member named `c_fpstatus'
core.c:212: structure has no member named `c_fpstatus'

looking at the core structure definition from /usr/include/sys/core.h
(which is included below) I find that the comment refers to c_fpstatus
but it is not to be found anywhere in /usr/include/*/*.
What am I missing? 

Thanks in advance,

Ralph Noack

 * The `old' core file consisted of dumping the u area.
 * In the `new' core format, this structure is followed
 * copies of the data and  stack segments.  Finally the user
 * struct is dumped at the end of the core file for programs
 * which really need to know this kind of stuff.  The length
 * of this struct in the core file can be found in the
 * c_len field.  When struct core is changed, c_fpstatus

 * make the floating pointing signal handler run more efficiently).
