I don't think I understand the problem you are trying to fix, and the
messages recorded by debbugs don't help (maybe some were lost or sent
in private email?).  Can you explain the relevance of globals.h to the
subject of this bug report?

Dependencies for header files are supposed to be recorded
automatically in the deps subdirectory, as part of compilation of C
source files, so how come something is not recompiled when its
dependency header file changes?  And I have _never_ seen any problems
with how we generate globals.h or detect that its contents changed.
