File core/src/fxge/win32/fx_win32_print.cpp (right):

https://codereview.chromium.org/1062863006/diff/1/core/src/fxge/win32/fx_win3...
core/src/fxge/win32/fx_win32_print.cpp:315: return TRUE;
This always returns true now but we can make another pass and deal with them.

Hmmm.  Wonder if we can write a clang plugin to find bool functions that always
