This little series adds a ldirname function to libiberty and makes the COBOL front-end to use it so it doesn't have to include the host's libgen.h.
The ldirname implementation doesn't exactly implement the same semantics than the POSIX dirname. In particular, it returns the empty string rather than "." when given pathnames that do not contain a directory separator. Note that lbasename doesn't mimic the POSIX basename interface neither, so I suppose this is ok. I tested this using the Algol 68 front-end, which is off-tree. I tested the COBOL change by running `make check-cobol', but I am not sure whether the small testsuite now in master covers this particular code change. Jose E.
