I would think that avoiding this would be very desirable.

Ok, I'll show my ignorance and purpose a very simple interface.

When the installed version is executed, it removes all includes
that were formally "fixed" (I understand this might be a tough problem
to determine exactly which files these are), it then "fixes" the current
set of system includes (their locations defined by the original
configure), and writes these "fixed" includes into the appropriate gcc-lib
include directory.

Show me the swiss cheese behind this simple proposal.
