Sorry this was so late in coming, especially to those who deserve my
thanks for helping out with the problem.

No one could actually nail it down. I had to track it through the
convoluted string of includes in the program to realize that etags was
deliberately turning off const with the lines
#undef const
#define const
Joe Mario pointed me right at the problem and, as it turned out, all I
needed to do was move the re-definition of const a few lines back in
the code and all was well.
Thanks to all who helped with this one. If nothing else, I understand
the CPP operation much better than I used to.
For those who care, here is my original query:
I was trying to build XEmacs on my new Alpha and got an error I simply
do not understand.
cc: Error: /usr/include/unistd.h, line 570: In this declaration, the type of
"rename" is not compatible with the type of a previous declaration of
"rename" at line number 166 in file /usr/include/stdio.h.
extern int rename __((const char *, const char *));
----------------^
cc: Error: /usr/include/errno.h, line 286: In this declaration, the type of
"perror" is not compatible with the type of a previous declaration of
"perror" at line number 216 in file /usr/include/stdio.h.
extern void perror __((const char *));
------------^
First, the claimed conflict is in the system header files. Second,
when I looked at the files in question, the definitions of "rename"
and "perror" are identical, as far as I can tell.
extern int rename __((const char *, const char *));
extern int rename __((const char *, const char *));
extern void perror __((const char *));
extern void perror __((const char *));
The only difference would appear to be space vs. tab. (And I even
tried changing one of the entries from a space to a tab, but that made
no difference.)
Can anyone explain this oddity? Am I mis-understanding what appears to
be a clear error?
