Maximum command line length now determined by execmax() function, which still just returns the compiled-in MAXLINE. p4transfer.py: Transferred from production |

Rewrite the past: update all jam's source with comments to reflect changes since about 2.3, very early 2001. Whitespace only change. === computer:1666: Change 37660 by seiwald@play-seiwald on 2002/11/06 22:41:35 Note: I regenerated jamgram.c on my linux 7.3 system prior to the submit, since patch was so unhappy trying to lay down the changes from Christopher's change. Presumably this is just due to different yacc/bison/whatever particulars on the system where Christopher made the changes originally. - rmg |

This change is integration history only. (Accept -ay'ed integrating: Change 216 by peter_glasscock@peter_glasscock on 1999/07/27 03:25:01 Integrate recent changes to public source So, these were apparently Matt's tweaks to changes being integrated from //public/jam, and we'll ignore them here. |

Jam 2.3. See RELNOTES for a list of changes from 2.2.x. Just about every source file was touched when jam got ANSI-fied. |
||
#2 | 212 | Perforce staff |
An interpretative integration of Peter Glasscock's -o file support. This is handled in the make1() routine, rather than in all the exec*.c files. -o x writes the actions to file x rather than actually running them. Implies -n (but not -d2). |
