preprocessor directives like
#line # 35 "/usr/include/iso/stdio_iso.h"
are typically inerted int generated or preprocessed C code to set the presumed line number and source file.
This can be useful so that error messages or macros that use __FILE__ or __LINE can tell you where the original code that genrerated the error came from

#define _SYS_VA_LIST_H
defines a preprocessor macro named _SYS_VA_LIST_H

pragmas cause the impementation to behave in an implementation-defined manner
