refactor: Fix pre-C++11 nested template parsing

[DevGeniusCode]

This PR resolves compilation errors in pre-C++11 compilers (such as VC6) caused by the >> token sequence in nested template declarations.

Instead of restructuring the code with typedefs, the issue is addressed by safely separating the consecutive closing angle brackets with an empty comment: >/* */>. This prevents the compiler from misinterpreting the sequence as a right-shift operator while preserving the original code structure and type definitions intact.

Key Details:

• Scope: A total of 68 instances of nested templates (found by searching for > >) were updated using this pattern.
• Edge Cases & Comments: Nested templates located within code comments were intentionally left unchanged.

Greptile Summary

This PR applies a targeted pre-C++11 compatibility fix across 48 files, replacing the > > spacing pattern in nested template closing brackets with >/* */>. The empty comment prevents old compilers like VC6 from tokenizing the two consecutive > characters as a single >> (right-shift) operator.

• ~68 typedef/declaration sites across headers and source files in Core/, Generals/, and GeneralsMD/ are updated with the >/* */> trick; instances inside code comments are intentionally left unchanged.
• The change is purely syntactic and has no semantic effect on any modern compiler (C++11 and later already handle >> correctly in template contexts), making this fully backward-compatible.

Confidence Score: 5/5

Safe to merge — all changes are purely syntactic comment insertions with no runtime behavior change.

The PR is a mechanical search-and-replace across 48 files: the only modification is inserting an empty /* */ comment between two consecutive > characters in nested template declarations. The /* */ token is stripped by the preprocessor and has zero semantic effect on any compiler. Modern compilers (C++11+) see identical code after preprocessing, and older compilers (VC6) now correctly tokenize the two angle brackets as separate tokens. No logic, data structures, or function signatures are altered.

No files require special attention. The most structurally complex changes are in AudioEvents.h (base class + four using declarations) and STLUtils.h (return types and constructor calls in function templates), both of which are correctly handled.

Important Files Changed

Filename	Overview
Core/Libraries/Source/WWVegas/WWAudio/AudioEvents.h	Fix applied to base class declaration and four using declarations inside AudioCallbackListClass template; all AUDIO_CALLBACK_STRUCT<T>/* */> substitutions are correct.
Core/Libraries/Source/WWVegas/WWLib/STLUtils.h	Fix applied to return types and constructor calls in get_range template functions; placement of /* */ between inner and outer > is correct in all four occurrences.
Core/GameEngine/Include/Common/FileSystem.h	Two typedef declarations (FilenameList, FileExistMap) corrected; multiline hash_map typedef correctly has the comment on the final template argument line.
Core/GameEngine/Source/Common/Audio/GameAudio.cpp	Two std::list<std::pair<...>>::iterator declarations patched; changes are consistent with the header-level typedef in GameAudio.h.
Generals/Code/GameEngine/Include/GameLogic/GameLogic.h	Two private hash_map typedefs (BuildableMap, ControlBarOverrideMap) updated; mirrored identically in GeneralsMD.
Core/Tools/matchbot/wlib/ustring.h	Fix applied to base class declaration and two pointer declarations inside operator==; all three uses of basic_string<charT, string_char_traits<charT>/* */> are syntactically correct.

Silly we need to do that 🥲

/**/ was not possible with clang format? It did work with VC6.
