Here is the input file

setup:  The input file is copied as the following files (all identical):

a1btest_test.cpp, a1btest_test.c, a1btest_test.h,a1btest_test.txt, a1btest_test.ini, 'a1btest_test.t t'

2 subdirectories are made:

a1btest_subdir1, a1btest_subdir2

Under each, a1btest_test.cpp is copied into it:

a1btest_subdir1/a1btest_test.cpp

a1btest_subdir2/a1btest_test.cpp

For each of the test cases below, .../ means the full path leading up to the spot where the test is being run.  To get the mark, you had to get the correct files and line numbers.
