- make "debug.h" a private header so that the DEBUG() macro does not interfere with Xcode Debug builds, which set DEBUG=1 - move all #include "debug.h" from headers into .c files - move 'struct idebug' into a new public header "idebug.h" so that "log.h" can be public - move HTTPD port number defs from "httpd.h" to "constants.h", so that "httpd.h" can be private and "conf.h" can be public - add missing nested includes so each header compiles stand-alone without error - #include "sodium.h" instead of <sodium.h> - #include "sqlite3.h" instead of <sqlite3.h> - add header guard to "fifo.h" - fix header guard in "sync_keys.h"
