This report is more useful. The first problem, a mistake in a header
guard, is easy to fix. The two related errors are caused by
'fexecve()' lacking at your system. I'll probably have to work around
this manually by using 'execve()' in such cases, since gnulib doesn't
seem to provide 'fexecve()'.

Since you were asking for help -- sorry, it won't work at your system
until this is worked around, unless there is a way to supplement your
system with the 'fexecve()' function.
