The old pcre code included with Privoxy had lots of fallthroughs
but that code is gone and the only implicit-fallthrough left is:
w32log.c: In function ‘LogWindowProc’:
w32log.c:1189:27: warning: this statement may fall through [-Wimplicit-fallthrough=]
1189 | g_bShowLogWindow = wParam;
| ~~~~~~~~~~~~~~~~~^~~~~~~~
w32log.c:1190:7: note: here
1190 | case WM_SIZE: /* note: implicit-fallthrough */
| ^~~~
# see: http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
# -Wall doesn't actually turn on all warnings, so add -Wextra
# but then plenty too many complaints by
-# -Wimplicit-fallthrough=3
-# too many warnings in pcre/study.c & pcre.c
# -Wmissing-field-initializers
# -Wsign-compare
# -Wtype-limits
