Problem Building Qt 5.2.1 Stable Branch

[EricRFMA]

Hello...

I seem to have chronic problems like this, that fix themselves for no apparent reason (which scares me), but I've tried two clean builds, with the same result.

The problem: When I do <code>make</code>, it chugs for a while then dies with the following:
@UIProcess/API/qt/qquickwebview.cpp:128:13: warning: enumeration values
'kJSTypeUndefined' and 'kJSTypeNull' not handled in switch [-Wswitch]
switch (JSValueGetType(context, value)) {
^
UIProcess/API/qt/qquickwebview.cpp:1921:41: error: conversion from
'const uint64_t' (aka 'const unsigned long long') to 'QFlag' is ambiguous
return int(Qt::InputMethodHints(state.inputMethodHints));
^~~~~~~~~~~~~~~~~~~~~~

I run configure thus:
@./configure -debug -prefix /Projects/Qt5.2.1 -no-pch -no-xcb -debug-and-release -sdk macosx10.8@

My preflight cleaning consists of:
@make clean
git reset --hard
git clean -dxf
git submodule foreach --recursive "git clean -dfx"@

Then, to update the pack:

@git pull
git submodule sync
git submodule update --recursive@

Then, I run <code>configure</code> as above (which may be redundant, not sure), then <code>make</code>.

So does this build error look familiar? Is something wrong with my clean & build procedure? I've done it twice (which is usually enough to make things magically work again), but same result. I'll try it yet again, since it takes a few hours, and cross my fingers until maybe I can a reply here.

Thanks!
