Replace AC_TRY_COMPILE and AC_LANG_
Autoconf 2.50 in 2001 made several macros obsolete. These include macros
for temporary changing the language - AC_LANG_SAVE, AC_LANG_CPLUSPLUS,
AC_LANG_C, and AC_LANG_RESTORE. Instead of these the AC_LANG_PUSH and
AC_LANG_POP macros should be used with later Autoconf versions.
AC_TRY_COMPILE macros should be replaced with AC_COMPILE_IFELSE.
