[Bug libc/12053] New: _NL_PAPER_HEIGHT/WIDTH disobeys LC_PAPER

[bkorb at gnu dot org]

You can print on letter sized paper and have
scrambled directory listings, or you can have ASCII ordered listings
but the last three lines of each printed page will appear after the
end of the sheet of paper, but you cannot get what you want --
normal "ls" output and letter sized paper.  The cause of the
problem, I've been told, is glibc.  If you set the environment
variable LC_PAPER to "letter", you should get letter sized pages.

Here is a sample program:

#include <stdio.h>
#include <locale.h>
#include <langinfo.h>

#define NL_PAPER_GET(x)         \
  ((union { char *string; unsigned int word; })nl_langinfo(x)).word

int main(int argc,char **argv)
{
  int w, h;

  setlocale (LC_PAPER, "");
  w = NL_PAPER_GET (_NL_PAPER_WIDTH);
  h = NL_PAPER_GET (_NL_PAPER_HEIGHT);
  printf ("height: %d\nwidth: %d\n", h, w);
  return 0;
}

printing programs depend upon nl_langinfo(_NL_PAPER_HEIGHT) to
determine the length of a page.  LC_PAPER is ignored and LC_ALL=C
is obeyed in this computation.  This is completely, totally
outrageously screwed up.

Whoever told you that made something up.  This never worked nor will it ever do.

The paper information is part of the normal locales and only such names work. 
If you don't like your locale's setting find a real, other locale and use that
name.  Making up something like 'letter' doesn't work.
