I installed gnu sed-1.11 on all of the machines I have available to
me.  Except for irix, all went well.

The Irix compiler understands const, even though __STDC__ is not
defined.  Function prototype conflicts between stdio.h and stdlib.h
occur because regex.h defines const to "", if __STDC__ is not defined.

[ system() is defined in both stdio.h and stdlib.h.  It is declared
  as ``extern int system(const char *s);''.  If regex.h is included
  between the two, the second declaration becomes ``extern int
  system(char *s);'', which conflicts with the first ]

One solution is to delay including GNU header files until the system
files have all been included --- But I used autoconf's AC_CONST
directive to conditionally add -Dconst= to DEFS.  I think this is the
better fix.

Enclosed is a patch which fixes regex.h to not define const, adds
AC_CONST to configure.in, and updates Makefile.in to document the
currenly used defines (-DNO_VFPRINTF -> -DHAVE_VPRINTF, etc.)
