Eradicate AC_TRY_COMPILE.
* aclang.m4 (AC_PROG_CC_STDC, AC_C_BIGENDIAN, AC_C_INLINE, AC_C_CONST, AC_C_VOLATILE, AC_F77_NAME_MANGLING): Use `AC_COMPILE_IFELSE'. * acspecific.m4 (AC_DECL_SYS_SIGLIST, _AC_CHECK_HEADER_DIRENT, AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_TYPE_SIGNAL, AC_FUNC_GETLOADAVG, AC_FUNC_SELECT_ARGTYPES, AC_STRUCT_TM, AC_CYGWIN, AC_MINGW32, AC_EMXOS2): Likewise. * tests/semantics.m4 (C keywords): Check that AC_C_CONST, AC_C_VOLATILE, and AC_C_INLINE function properly with GCC.
