Some .cc files are missing config.h include
Per the coding guidelines
top level config.h generated by autoconf should also be included before other generic header files
This doesn't imply that all of them should have it, but there doesn't seem to be a reason why a number of 32 non-generated
.cc files are missing the
config.h include. This is dangerous because you could be missing a defined macro in some code and not realize it.
