Hi, gnulib fails to build on Mac OS X 10.4 Tiger: get_ppid_of.c:36:22: error: libproc.h: No such file or directory
libproc.h was introduced in Mac OS X 10.5 Leopard. This problem affects gettext 0.21 which includes this version of gnulib. This is a problem because so many things depend on gettext. This was reported to MacPorts here: https://trac.macports.org/ticket/64102 Previous versions of gnulib and gettext did not use libproc.h and so did not have this problem. Perhaps some solution can be found to make the use of libproc.h optional so that systems without that header can still be used?
