well, currently Qt >= 3.3.0 enables PCH support if it detects that the 
compiler is gcc and that it supports the -x option. I think you can manually 
disable the pch support with the configure script.  
 
There are a few possible solutions:  
 
a) make the default for PCH to off in newer Qt 3.3 releases. I guess 
TT would do that change if asked to.  
 
b) disable -x flag unless -yes-i-know-it-is-buggy flag is given. this way 
the configure would fail, and not enable PCH.  
 
right now the only problem I see with PCH except this bug is however that 
you cannot combine the PCH header for C and C++ compilations.
