compile error for mkString on alpha (PR#332)
Full_Name: Albrecht Gebhardt
Version: 0.90.0
OS: osf4.0
Submission from: (NULL) (143.205.61.73)
I had to apply the following patch to be able to compile on
an alpha with DU 4.0E:

Without the patch I got:

SEXP mkString(const char *s)
-----^
Then I looked at the preprocessed sources:
cc -I. -I../include -I../../src/include -I/usr/local/include -DHAVE_CONFIG_H
-ieee_with_inexact -g -E gram.c > gram.E
grep -n mkString gram.E
8915:SEXP mkString(const char*);
9564:SEXP mkString(const char *);
11995:SEXP mkString( char *s)
12179: protect(yylval = mkString(yytext));
I don't know why the third occurrence of "mkString(const char*);"
(line 11995 of preproccessor output) has the "const" removed, it is
present in
the
source! But the trick with typedefing "const char" to
"cconst" in the patch
above works.
BTW, there are many warnings about mixing "char" and "unsigned
char",
not only in gram.c!

If not, `const' is defined empty. Can you look at you Rconfig.h and see if anything is done about const there? Can you also look at config.log?
