This requires removing them from the C package so they can be exported from the KERNEL package. To do this, use the bootstrap file boot-2021-07-1 to unintern these from the C package. Then update the KERNEL package to export these symbols. Finally, update the definition of FLOAT-INT-EXPONENT to use KERNEL:DOUBLE-FLOAT-INT-EXPONENT instead of C::DOUBLE-FLOAT-INT-EXPONENT. - - - - - 0dac88e6 by Raymond Toy at 2023-02-25T07:24:24-08:00 Add comment on what the bootfile is doing. - - - - - 7338f627 by Raymond Toy at 2023-02-25T07:25:19-08:00 Update CI to use the bootstrap file.
