Is your feature request related to a problem? Please describe.

Currently, if a code uses except + or something similar, the generated code will have #include "ios" which causes a compilation failure with fatal error: ios: No such file or directory error message, which is confusing.

#1910 sagemath/sage#39046 (comment)

Describe the solution you'd like.

We modify the generated code to say e.g.

#ifdef __cplusplus
#include "ios"
#else
#error "C++ is required to compile this file."
#endif

Describe alternatives you've considered.
