 5.2 Examining Syntax
 ====================
 
 To check for a syntax feature of the C, C++ or Fortran 77 compiler, such
 as whether it recognizes a certain keyword, use `AC_TRY_COMPILE' to try
 to compile a small program that uses that feature.  You can also use it
 to check for structures and structure members that are not present on
 all systems.
 
  -- Macro: AC_TRY_COMPILE (INCLUDES, FUNCTION-BODY, [ACTION-IF-FOUND [,
           ACTION-IF-NOT-FOUND]])
      Create a C, C++ or Fortran 77 test program (depending on which
      language is current,  Language Choice), to see whether a
      function whose body consists of FUNCTION-BODY can be compiled.
 
      For C and C++, INCLUDES is any `#include' statements needed by the
      code in FUNCTION-BODY (INCLUDES will be ignored if the currently
      selected language is Fortran 77).  This macro also uses `CFLAGS'
      or `CXXFLAGS' if either C or C++ is the currently selected
      language, as well as `CPPFLAGS', when compiling.  If Fortran 77 is
      the currently selected language then `FFLAGS' will be used when
      compiling.
 
      If the file compiles successfully, run shell commands
      ACTION-IF-FOUND, otherwise run ACTION-IF-NOT-FOUND.
 
      This macro does not try to link; use `AC_TRY_LINK' if you need to
      do that ( Examining Libraries).
