It looks like some update caused src/httpserver.c to need to include deque when building with GCC. Otherwise it fails to compile with:
httpserver.cpp:74:10: error: 'deque' in namespace 'std' does not name a template type
74 | std::deque<std::unique_ptr<WorkItem>> queue;
| ^~~~~
httpserver.cpp:33:1: note: 'std::deque' is defined in header '<deque>'; did you forget to '#include <deque>'?
32 | #include <support/events.h>
+++ |+#include <deque>

httpserver.cpp: In member function 'bool WorkQueue<WorkItem>::Enqueue(WorkItem*)':
httpserver.cpp:92:13: error: 'queue' was not declared in this scope; did you mean 'Enqueue'?
92 | if (queue.size() >= maxDepth) {
| ^~~~~

95 | queue.emplace_back(std::unique_ptr<WorkItem>(item));
