Hello.

Test 3: Solving c:../../../../../../djgpp.204/tests/libc/compat/unistd/test1

__symlink_path:
"c:../../../../../../djgpp.204/tests/libc/compat/unistd/test1"

__real_path:
""

I have plain CVS, plus these diff below. If I don't the diff below applied,
then it looked like __real_path contained the result of the last
__solve_symlinks call (__symlink_path ending with file1 instead of test1).

Perhaps you could e-mail me your version of the xsymlink.c test sources?

What would you do, if we could?
