I'm updating my gcc/g++ to 2.95.2 so that I can compile the latest Octave
CVS archives.

Compiling liboctave/oct-time.cc gives errors:

oct-time.cc:182: `struct tm' has no member named `tm_zone'
oct-time.cc: In method `void octave_base_tm::init(void *)':
oct-time.cc:229: `struct tm' has no member named `tm_zone'
oct-time.cc: In method `void octave_strptime::init(const string &, const
string &)':
oct-time.cc:273: `struct tm' has no member named `tm_zone'

There was previously an error near line 80 of this file.  I worked my way
back to time.h on my system, which defines struct tm with:

#ifdef _OSF_SOURCE
        long    tm_gmtoff;
        char    *tm_zone;
#else
        long    __tm_gmtoff;
        char    *__tm_zone;
#endif

It's not clear to me why this doesn't cause problems in the configure
script.  Nevertheless, I modified oct-time.cc near line 80 to read:

#if defined (HAVE_TM_ZONE)
  std::string s = tm.zone ();
  char *ps = strsave (s.c_str ());
#ifdef _OSF_SOURCE
  t.tm_zone = ps;
#else
  t.__tm_zone = ps;
#endif
#endif

which seems to fix the compiler problem.

Do other alpha users have suggestions on a clean way to fix this problem?
One
may either have configure define _OSF_SOURCE (to define the tm struct as
expected) or else I can modify oct-time.cc as above in each place where
tm_zone is referenced.  I don't like either of these solutions, since this
problem does not show up when I manually compile the conftest.c program
generated by configure to test for tm.tm_zone.
