[Rd] [patch] R-1.9.0: compile error without nl_langinfo(CODESET) (PR#6789)

[bunk at fs.tum.de]

I got the following compile error in R-1.9.0 on NetBSD 1.5:
 
<--  snip  -->
 
...
gcc -I../../src/extra/zlib -I../../src/extra/bzip2
-I../../src/extra/pcre -I. -I../../src/include -I../../src/include -I/usr/local/include  
-DHAVE_CONFIG_H   -O2 -mcpu=v8 -c main.c -o main.o
main.c: In function `setup_Rmainloop':
main.c:463: `CODESET' undeclared (first use in this function)
main.c:463: (Each undeclared identifier is reported only once
main.c:463: for each function it appears in.)
make[3]: *** [main.o] Error 1
make[3]: Leaving directory `/aux/adrian/build/R-1.9.0/src/main'
 
<--  snip  -->
 
NetBSD 1.5 has a nl_langinfo() in langinfo.h but no CODESET.
 
A proposed patch (based on codeset.m4 from GNU gettext) is below.
