First attempt to hand-merge Ryan's Linux and Mac OS X port. This was a _ton_ of changes, made 15 years ago, so there are probably some problems to work out still. Among others: Engine/Base/Stream.* was mostly abandoned and will need to be re-ported. Still, this is a pretty good start, and probably holds a world record for lines of changes or something. :)

Commented out unused functions and variables many unused functions and variables are now commented out You'll still get tons of warnings, which should mostly fall in one of the following categories: 1. Unnecessary variables or values generated from .es scripts 2. Pointers assigned to from functions with side-effects: DO NOT REMOVE! Like CEntity *penNew = CreateEntity_t(...); - even if penNew isn't used, CreateEntity() must be called there!

First attempt to hand-merge Ryan's Linux and Mac OS X port. This was a _ton_ of changes, made 15 years ago, so there are probably some problems to work out still. Among others: Engine/Base/Stream.* was mostly abandoned and will need to be re-ported. Still, this is a pretty good start, and probably holds a world record for lines of changes or something. :)

First pass at cleaning out 64-bit issues. Touches a lot of code to remove long constants like "1L", so this patch is large and ugly, but I think it makes all those Clamp() calls look nicer in the long run. Most of the game is 64-bit clean, since we can build without assembly code now. I've marked the things that are obviously still wrong with STUBBED lines. That being said: a 64-bit build can already run the demos mostly correctly, so we're actually almost there! There are a few obvious things that are obviously wrong, to be fixed.

First attempt to hand-merge Ryan's Linux and Mac OS X port. This was a _ton_ of changes, made 15 years ago, so there are probably some problems to work out still. Among others: Engine/Base/Stream.* was mostly abandoned and will need to be re-ported. Still, this is a pretty good start, and probably holds a world record for lines of changes or something. :)

Unnecessary variables or values generated from .es scripts 2. Pointers assigned to from functions with side-effects: DO NOT REMOVE! Like CEntity *penNew = CreateEntity_t(...); - even if penNew isn't used, CreateEntity() must be called there!

First attempt to hand-merge Ryan's Linux and Mac OS X port. This was a _ton_ of changes, made 15 years ago, so there are probably some problems to work out still. Among others: Engine/Base/Stream.* was mostly abandoned and will need to be re-ported. Still, this is a pretty good start, and probably holds a world record for lines of changes or something. :)

First pass at cleaning out 64-bit issues. Touches a lot of code to remove long constants like "1L", so this patch is large and ugly, but I think it makes all those Clamp() calls look nicer in the long run. Most of the game is 64-bit clean, since we can build without assembly code now. I've marked the things that are obviously still wrong with STUBBED lines. That being said: a 64-bit build can already run the demos mostly correctly, so we're actually almost there! There are a few obvious things that are obviously wrong, to be fixed.

First attempt to hand-merge Ryan's Linux and Mac OS X port. This was a _ton_ of changes, made 15 years ago, so there are probably some problems to work out still. Among others: Engine/Base/Stream.* was mostly abandoned and will need to be re-ported. Still, this is a pretty good start, and probably holds a world record for lines of changes or something. :)
