[BUG] "#if defined(HAVE_CONFIG_H)" not interpreted

[drok]

Describe the bug

This code fragment is not interpreted correctly (ie, vscode is not aware that HAVE_CONFIG_H is defined). As a result, the deflateBound definition appears active even though HAVE_DECL_DEFLATEBOUND is set to 1 in build-config.h

#if defined(HAVE_CONFIG_H)
#include "build-config.h"
#endif

#if !HAVE_DECL_DEFLATEBOUND
#define deflateBound(c,s)  ((s) + (((s) + 7) >> 3) + (((s) + 63) >> 6) + 11)
#endif

Steps to reproduce the behavior:

AC_CHECK_DECLS([deflateBound],,,[[#include <zlib.h>]])

The "define deflateBound" line should be dimmer (not compiled) because zlib does implement the function, and HAVE_DECL_DEFLATEBOUND is set to 1 in build-config.h
