No.

PCH is nowhere close to "release" state. There are numerous issues with 
PCH on MSVC:
1. Property propagation (I've raised this issue before).
2. Debug information: PCH is does not work well with C7-style debug info 
  and database-style debug storage is currently broken ("# not used yet").
3. Problems with PCH and static libraries.
4. It would be nice if Boost libraries themselves used precompiled 
headers (at least for testing purposes).
5. PCH on GCC is broken (the last time I checked).
6. Some other subtle issues I can't remember.
