Not quickly, no. But neither does C++ (how long does it take to compile Clang?) and people manage fine.
Faster would obviously be better, but it's not big enough of a deal to cancel out all the advantages compared to C.
I once moved a C++ project to C, and compile times went from 15 minutes to 5 seconds. It was a huge productivity boost. LLVM being slow to compile is also one of the reasons the Zig folk are looking to make it an optional dependency.
I remember a project that used boost for very few things, but it included a single boost header in almost every file. That one boost header absolutely inflated the build times to insane levels.
