// This header file defines a set of macros for checking the presence of
// important compiler and platform features. Such macros can be used to
// produce portable code by parameterizing compilation based on the presence or
// lack of a given feature.
//
// We define a "feature" as some interface we wish to program to: for example,
// a library function or system call. A value of `1` indicates support for
// that feature; any other value indicates the feature support is undefined.
//
// Example:
//
// Suppose a programmer wants to write a program that uses the 'mmap()' system
// call. The Abseil macro for that feature (`ABSL_HAVE_MMAP`) allows you to
// selectively include the `mmap.h` header and bracket code using that feature
// in the macro:
//
//   #include "absl/base/config.h"
//
//   #ifdef ABSL_HAVE_MMAP
//   #include "sys/mman.h"
//   #endif  //ABSL_HAVE_MMAP
//
//   ...
//   #ifdef ABSL_HAVE_MMAP
//   void *ptr = mmap(...);
//   ...
//   #endif  // ABSL_HAVE_MMAP
