/tset/XPG4.os/wprintpos/wcwidth/T.wcwidth (build)Specification Base Definitions Issue 6 Location in Spec pubs.opengroup.org/onlinepubs/009695399/functions/mbtowc.html
ISO/IEC 9899:1999 Section 7.1.4Problem Summary Portions of the VSX4 test suite fail to compile. Problem Text When we build the VSX4 test suite (version 4.7.18 and earlier versions)
it fails to compile. The
compilation failures occur in two source files:
/tset/XPG4.os/wprintpos/wcswidth/wcswidth.c
/tset/XPG4.os/wprintpos/wcwidth/wcwidth.c
In each of these files, the function mbtowc() is used. This function is
declared in the header
<stdlib.h>, as specified in
https://pubs.opengroup.org/onlinepubs/009695399/functions/mbtowc.html.
But the header file
<stdlib.h> is not included in either of these source files. Our compiler
issues the error
error: implicit declaration of function 'mbtowc' is invalid in C99
and fails to generate object files. This is consistent with the
requirements of ISO/IEC 9899:1999.
Adding the line
#Include <stdlib.h>
to each of these source files resolves the issue.Test Output From the VSX4 Build journal file:

build failures it is not suitable for a TSD.
There is also no need to issue a patch, since a simple work-around
exists. The submitter should add the following lines to SRC/vsxconfig.h
and then rerun the top-level make and tcc -b.
/****** <wchar.h> - Missing elements ******/
/****** Start of Definitions for file wchar.h ******/

It is recommended that this TSD request is rejected.
