22 | At one point, this was defined in config.h, meaning that changing | |
23 | PURESIZE would make Make recompile all of Emacs. But only a few | |
d427b66a | 24 | files actually use PURESIZE, so we split it out to its own .h file. |

26 | Make sure to include this file after config.h, since that tells us |
27 | whether we are running X windows, which tells us how much pure | |
28 | storage to allocate. */ | |
