In `psrand.h` it attempts to undefine RAND_MAX and then redefine it.
This may work on some compilers but G++/Clang. To resolve this error
RAND_MAX was renamed to D3_RAND_MAX but **only** in files that
included `psrand.h`. The code behavior should restored to that of the
official release.
Added installation steps for all built targets. Added FORCE_PORTABLE_INSTALL cmake option that controls portable installation (only supported for now).
Join the license header with historical comments using a separator so IDEs can correctly parse the initial header.
Also use .gitattributes to ensure all files are LF.
* Begin by marking functions and variables as static when needed.
* More work.
* More work.
* More pokes.
* More work.
* More work.
* Initial work on the netgames.
* Revert changes to the license header on source files.
* clutter.cpp poke.
* One final poke.
* Move some declarations to headers:
Move paged_in_count and paged_in_num to gamesequence.h
Move DoneLightInstance and StartLightInstance to polymodel.h
* Look over the AI script/plug-ins.
* Going over the changes one last time.
* Fix rebase errors.
* More migration from bare statics to static inlines.
The vast majority of this is fixing up `char *` that should be `const char *`
but a handful of other fixes, like potential buffer overflows that GCC
noticed, etc, were applied as well.
This removes `-Wno-write-strings` from CMakeLists.txt, as it is no longer
necessary, as there is no longer a flood of compiler warning spam when
building.
This does not fix all compiler warnings; there are still a handful, and they
are legitimate, but they can be dealt with in a future commit.
At this point, all remaining references to `MACINTOSH` are either part
of multi-value conditionals that `unifdef` was unable to determine the
final value for, or a `#define`, or a comment. I manually go through the
files with a Ctrl+Shift+F search (ignoring legacy/, to preserve useful
historic knowledge) and clean up each usage.
As part of that search, I discovered `lib/mac/` which I deleted wholly.
Test Plan:
On Mac, build both Debug and Release
```
cmake --build --preset mac --config Debug
cmake --build --preset mac --config Release
```
The MACINTOSH define refers to MacOS Classic (not OS X) which we do not
plan to support. Rather than carry the cruft forever, let's delete it.
NOTE: legacy/ is unused but we're keeping it around, so MACINTOSH uses
there are left alone.
Process used for this commit:
```
git rm -r mac
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" \) \
-exec unifdef -UMACINTOSH -o {} {} \;
git restore legacy
git add .
```
Test Plan:
On Mac, build both Debug and Release
```
cmake --build --preset mac --config Debug
cmake --build --preset mac --config Release
```
None of these sources are referenced, either directly or indirectly,
in any CMakeLists.txt file.
NOTE: All of legacy/ is unused, but we're keeping it around.
Process for this commit: (in bash)
**NOTE: THIS MUST BE DONE ON A CASE-SENSITIVE FILESYSTEM**. There are a
few instances of differing-in-case-only (hogmaker vs HogMaker, etc) that
will catch you out otherwise.

# -f means load patterns from the given file

Test Plan:
On all three of `[win, mac, linux]`:
```
cmake --preset <platform>
cmake --build --preset <platform> --config Debug
cmake --build --preset <platform> --config Release
