| 20 | ?S:d_csh: | |
| 21 | ?S: This variable conditionally defines the CSH symbol, which | |
| 22 | ?S: indicates to the C program that the C-shell exists. | |
| 23 | ?S:. | |
| 24 | ?S:full_csh: | |
| 25 | ?S: This variable contains the full pathname to 'csh', whether or | |
| 26 | ?S: not the user has specified 'portability'. This is only used | |
| 27 | ?S: in the compiled C program, and we assume that all systems which | |
| 28 | ?S: can share this executable will have the same full pathname to | |
| 29 | ?S: 'csh.' | |
| 30 | ?S:. | |
| 31 | ?C:HAS_CSH: | |
| 32 | ?C: This symbol, if defined, indicates that the C-shell exists. | |
| 33 | ?C:. | |
| 34 | ?C:CSH: | |
| 35 | ?C: This symbol, if defined, contains the full pathname of csh. | |
| 36 | ?C:. | |
| 37 | ?X: Previously, I just did $d_csh CSH "$full_csh", but that caused | |
| 38 | ?X: problems on VMS where the config.sh extraction program changes | |
| 39 | ?X: $undef to a real cpp undef, and they then had #undef CSH "" | |
| 40 | ?X: which the compiler didn't like. It's easy to work around this, | |
| 41 | ?X: so I did. --AD 3/1998. | |
| 42 | ?X: And we don't want to define CSH if !HAS_CSH, but we don't want | |
| 43 | ?X: those lines in config.h if they don't need CSH, so protect with ?CSH | |
| 44 | ?X: and not ?%<. --RAM, 15/02/2004 | |
