In GNU tar 1.07 the portability considerations for getwd() are divided between two files: port.c and tar.c. In port.c is an implementation that opens a pipe to pwd (slow), and in tar.c getcwd() is used instead if MSDOS is defined. But since MSDOS isn't the only system that has getcwd() but not getwd() (my System V machine, for example), and since getwd() can be implemented as a call to getcwd() on those systems, I think that the code in tar.c should be removed and an alternate definition of getwd(), in terms of getcwd(), be made available in port.c. Perhaps when both NEED_GETWD and (a new macro) HAVE_GETCWD are defined. -- David J. MacKenzie <djm@wam.umd.edu>
