Yes, it will cause numerous compiler errors if it’s compiled as C code. If it’s being compiled as C++ instead, then it will compile fine. For example, GCC has the
-xoption to select the language to compile as, so you can compile a.cas C++ if you want with-x c++. Likewise, the Microsoft Visual C++ compiler has the options/Tcand/Tpto select a source language of C and C++ respectively.I suggest you fix your build system so that it doesn’t pass the
-x c++or/Tpflag to files not ending with typical C++ source file extensions (.cc,.cpp,.cxx,c++, and.C, though the last three are quite rare).
