#7 | 2519 | Miklos Fazekas | Sync to 2.5rc1 | ||
#6 | 1590 | Miklos Fazekas | Fixed a bug with my Mac/ date implementation&minor changes | ||
#5 | 1573 | Miklos Fazekas | Merge to jam mainline. | ||

#3 | 1395 | Miklos Fazekas | Merge with main jam | ||
#2 | 1219 | Miklos Fazekas |
MPW related fixes: - support for longer than 255 pahtnames - fixed problems with handling of paths - fix: Mac file system is case insensitive - code is compatible with MrC and MWCCP |
||
#1 | 1212 | Miklos Fazekas | Created a Jam branch | ||
//guest/perforce_software/jam/src/jam.c | |||||
#7 | 486 | Perforce staff |
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. |
||
#6 | 213 | Perforce staff | Peter Glasscock's MPW port. | ||
#5 | 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). |
||
#4 | 76 | Laura Wingerd |
Integrate command-block-too-long fix, plus minor doc updates. Jam/MR release level is now 2.2.5. (change 72, change 73, change 74, change 75) |
||
#3 | 5 | Perforce maintenance | Jam/MR 2.2.4 (HDRPATTERN, JAMUNAME, JAMSHELL, plus misc tweaks) | ||
#2 | 3 | Perforce maintenance | Jam/MR 2.2.1 (fix for NT handle leak) | ||
#1 | 2 | laura | Add Jam/MR 2.2 source |
