Hi all,

I think we should decide whether or not to give up precompiled header support 
on gcc.

Precompiled header support is marked as EXPERIMENTAL in configure script for a 
very 
long time. On Windows, the buildbot is using pch and the featue is well tested 
these 
days.

Meanwhile no bot is enabling pch on gcc platforms and I also experienced some 
unstability in gcc's pch feature.

Fortunately, mingw gcc-4.2.1 carries relatively stable pch capability and I am 
trying 
it at each milestone.

Pch on gcc requires that the headers can be compiled in both exception handling 
enabled 
and disabled and that the precompiled header is included not more than once in 
each 
compilation unit. Some new code violates these conditions from time to time and 
I am 
raising issues like i#11379.

As the conditions for writing code with precompiled headers are not well 
documented and 
pch on gcc is not so stable, these issues take long time to be fixed.

I feel like I am the only one using pch on gcc.
If we do not want to keep pch feature on gcc, we should remove it in configure.
