qt5-qttools:remotecontrol.cpp:147: poor choice of local data type ?

I just ran the static analyser "cppcheck" over the source code
of qttools-opensource-src-5.2.0-beta1

It said

[remotecontrol.cpp:147]: (warning) Storing getc() return value in char variable and then comparing with EOF.

Source code is

while (true) {
char c = getc(stdin);
if (c == EOF || c == '\0')
break;

The test for c against EOF will always fail. Suggest change
data type of c from char to int.
