I encountered a few bugs (compilation and others) in the newlib-4.3.0.20230120 release. Compiling using GCC version 12.2.0 for FreeRTOS and an in-house processor.


  1.  The function declaration for mcwidth in newlib/libc/string/wcwidth.c does not match the prototype in newlib/libc/include/wchar.h .

  1.  Should be including sys/types.h not sys/_types.h  in newlib/libc/include/stdio.h

  1.  In order to build boost and some other third party libraries, need to have the following defined in newlib/libc/include/glob.h

#define GLOB_NOMATCH    (-3)    /* No matches found.  */
#define GLOB_NOSYS      (-4)    /* Not implemented.  */
/* Previous versions of this file defined GLOB_ABEND instead of
 *    GLOB_ABORTED.  Provide a compatibility definition here.  */
#define GLOB_ABORTED GLOB_ABEND

  1.  In newlib/libc/locale/locale.c need to add

  int ret = 0;
inside the first #else clause in function __loadlocale . This is after the #ifdef __CYGWIN__ line.

  1.  The return type for pthread_yield should be int not void in newlib/libc/include/pthread.h.  This matches both Linux and FreeRTOSLabs posix threads.
