by combining all files into single object file, linker has less oportunity to remove unused code. This leads to (sometimes significantly) larger executable binaries. For this reason, we do not recommend (and have off by default) BLITZ for release builds and if possible, we use precompiled headers for release builds.

At least for GCC, your experiments would lead me to use BLITZ for release builds, with the following options:

-ffunction-sections -fdata-sections -Wl,--gc-sections

Best of BLITZ, with much more unused code removed!

Anyway thanks for working on PCH.
