This is what it looks like after preprocessing:

UINT __attribute__((__stdcall__)) __attribute__((__force_align_arg_pointer__)) pa_present(MSIHANDLE hinst)
{
...
for (winetest_start_todo(!MsiGetMode(hinst, MSIRUNMODE_SCHEDULED)); winetest_loop_todo(); winetest_end_todo())
    check_reg_str(hinst, key, name_dotnet, "rcHQPHq?CA at Uv-XqMI1e>Z'q,T*76M@=YEg6My?~]");
    RegCloseKey(key);

This indentation (supposedly) suggests that the RegCloseKey(key) call should be
inside the 'for' body.

If I add braces:

UINT __attribute__((__stdcall__)) __attribute__((__force_align_arg_pointer__)) pa_present(MSIHANDLE hinst)
{
...
for (winetest_start_todo(!MsiGetMode(hinst, MSIRUNMODE_SCHEDULED)); winetest_loop_todo(); winetest_end_todo()) {
    check_reg_str(hinst, key, name_dotnet, "rcHQPHq?CA at Uv-XqMI1e>Z'q,T*76M@=YEg6My?~]");
}
    RegCloseKey(key);

or if I indent like this:

UINT __attribute__((__stdcall__)) __attribute__((__force_align_arg_pointer__)) pa_present(MSIHANDLE hinst)
{
...
    for (winetest_start_todo(!MsiGetMode(hinst, MSIRUNMODE_SCHEDULED)); winetest_loop_todo(); winetest_end_todo())
        check_reg_str(hinst, key, name_dotnet, "rcHQPHq?CA at Uv-XqMI1e>Z'q,T*76M@=YEg6My?~]");
    RegCloseKey(key);}

the warning goes away. Does that answer your question?
