Ick, this is an accidental leftover from the earlier iteration of the patch, which moved that part to a separate line (inside my gross GIT_REAL_POT conditional). The extra line went away, but I forgot to add $(LIB_H) back in here. Thanks for noticing. Here's a revised version of the patch which fixes it (and I double-checked to make sure it continues to not execute the find unless you are doing a "make pot"). -- >8 -- Subject: Makefile: use `find` to determine static header dependencies Most modern platforms will use automatically computed header dependencies to figure out when a C file needs rebuilt due to a header changing. With old compilers, however, we fallback to a static list of header files. If any of them changes, we recompile everything. This is overly conservative, but the best we can do on older platforms. It is unfortunately easy for our static header list to grow stale, as none of the regular developers make use of it. Instead of trying to keep it up to date, let's invoke "find" to generate the list dynamically. Since we do not use the value $(LIB_H) unless either COMPUTE_HEADER_DEPENDENCIES is turned on or the user is building "po/git.pot" (where it comes in via $(LOCALIZED_C), make is smart enough to not even run this "find" in most cases. However, we do need to stop using the "immediate" variable assignment ":=" for $(LOCALIZED_C). That's OK, because it was not otherwise useful here.
