 There are some methods RTEMS cannot support. For example, fork(), exec(),
 and posix_spawn() require multiple processes which RTEMS is not designed
 to support.

 In the Compliance Guide, a new code (unsupportable?) will have to be added
 to the spreadsheet. The Python script that processes this into the
 document will have to be enhanced to recognize this.

 In the POSIX Users Guide, add a chapter "Unsupportable Methods" which has
 a section per header file and subsections for each reason a class of
 methods defined in that header file cannot be supported.

 Hopefully, capturing this information will help users and prevent
 developers from rediscovering why something is not supported and can not
 be.
