- Deduplicates unused IDC_REGEDIT MENU vs. actually used IDR_REGEDIT_MENU - shrinks the binary size, GCC8.4.0dbg build shrinks from 1.052.672 -> 1.049.600 bytes - that also solves a few FIXME's, e.g. in hu-HU, pl-PL, sl-SI, sq-AL, tr-TR, uk-UA - translates the help-popup string in th-TH.rc - slightly tweak some headers to be a bit closer to newstyle without going all the way - also link to LPGL2.1+ in the source files to reduce the wall-of-text, also some other whitespace tweaks in those, but no functional change - security.c: vertical-compactness-whitespace-changes aim to get HeapAlloc closer to HeapFree - id-ID.rc: "&Data nilai" and "&Nama nilai" does exist in 4 dialogs, Harmonize them - pt-PT.rc: add 2 missing accels in IDD_EDIT_STRING - edit.c: 3x ARRAY_SIZE - the most review-worthy change in the actual .h/.c files is clb.c the change from ClbWndClass.hInstance = hinstDLL, ClbWndClass.hIcon = NULL; to ClbWndClass.hInstance = hinstDLL; ClbWndClass.hIcon = NULL; - clb.c the stripped INT_PTR-cast for EndDialog() was Co-authored-by: Katayama Hirofumi MZ <katayama.hirofumi.mz@gmail.com>
