Philip points out that subversion/libsvn_subr/errorcode.inc and subversion/libsvn_subr/config_keys.inc are not regenerated when svn_error_codes.h and svn_config.h (respectively) change.
The fix would be to write a Makefile.in rule that regenerates (just) the .inc file when the respective .h file changes. The files arae regenerated by these lines in gen-make.py: generator.write_errno_table() generator.write_config_keys() I note that the line before those two is write_sqlite_headers(), which already works correctly (touching .sql regenerates its .h). config_keys.inc is new from today, errorcode.inc has around since 1.8. I'm not sure what's the situation in the windows build with respect to this issue. Daniel
