Notice how this tiny shell script drives
the compiled program. There is no need to
choose unique names from within the C code, nor
even to clean up when done, since it's run from
within a just-created directory that's removed upon completion
of this single test. Also, there's no more need for the $EXE suffix,
since we're using PATH.
#!/bin/sh
: ${srcdir=.} ${builddir=.}
. $srcdir/init.sh --set-path=$builddir
fail=0;
test-pread || fail=1
Exit $fail
