| 1417 | nonstandard directory <lib dir> |
| 1418 | LIBS libraries to pass to the linker, e.g. -l<library> |
| 1419 | CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if |

| 1421 | CXX C++ compiler command |
| 1422 | CXXFLAGS C++ compiler flags |
| 1423 | CPP C preprocessor |
| 1424 | |
| 1425 | Use these variables to override the choices made by `configure' or to help |

| 7360 | Here is a matrix of mmap possibilities: |
| 7361 | mmap private not fixed |
| 7362 | mmap private fixed at somewhere currently unmapped |
| 7363 | mmap private fixed at somewhere already mapped |
| 7364 | mmap shared not fixed |
| 7365 | mmap shared fixed at somewhere currently unmapped |
| 7366 | mmap shared fixed at somewhere already mapped |
| 7367 | For private mappings, we should verify that changes cannot be read() |
| 7368 | back from the file, nor mmap's back from the file at a different |
| 7369 | address. (There have been systems where private was not correctly |
| 7370 | implemented like the infamous i386 svr4.0, and systems where the |
| 7371 | VM page cache was not coherent with the file system buffer cache |
| 7372 | like early versions of FreeBSD and possibly contemporary NetBSD.) |
| 7373 | For shared mappings, we should conversely verify that changes get |
| 7374 | propagated back to all the places they're supposed to be. |
| 7375 | |
| 7376 | Grep wants private fixed already mapped. |
| 7377 | The main things grep needs to know about mmap are: |
| 7378 | * does it exist and is it safe to write into the mmap'd area |
| 7379 | * how to use it (BSD variants) */ |
