Bug ID: 70917
Summary: out-of-date documentation for character set support
and environment variables
Product: gcc
Version: 6.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: wilson at gcc dot gnu.org
Target Milestone: ---
In the doc section Environment Variables Affecting GCC
https://gcc.gnu.org/onlinedocs/gcc-6.1.0/gcc/Environment-Variables.html#Environment-Variables
Near the bottom, it mentions that you can set LANG to C-JIS etc, but the code
that supported this was in mbchar.c, and that file was deleted in 2003.
It also mentions near the top that you can set LC_CTYPE, I found this support
in libcpp/charset.c, and it is disabled with an ifdef because it caused
problems with non-ascii names.
I think these two parts should be removed, or maybe LC_CTYPE commented out, and
maybe add a comment to libcpp/charset.c to re-add LC_CTYPE docs if it ever gets
re-enabled.
LC_MESSAGES seems correct.
LC_ALL refers to LC_CTYPE which is wrong if LC_CTYPE docs are removed,
otherwise it looks OK.
I'm not an expert in this area, so I'm not sure if I got this all right.
