Macros used by AC_LANG_COMPILER macros shall not AC_REQUIRE
AC_LANG_COMPILER by the way of AC_COMPILE_IFELSE etc. * acspecific.m4 (_AC_EXEEXT): Use _AC_LINK_IFELSE, not AC_LINK_IFELSE to avoid AC_REQUIREing AC_PROG_CC which precisely requires _AC_EXEEXT. Don't run _AC_CYGWIN, _AC_MINGW32, _AC_EMXOS2. * aclang.m4 (_AC_PROG_F77_G): Use _AC_COMPILE_IFELSE, not AC_COMPILE_IFELSE. (_AC_LANG_COMPILER_WORKS): Use _AC_LINK_IFELSE, not AC_LINK_IFELSE.

* Autoconf 2.50

** AC_EXEEXT, AC_OBJEXT
|
||||
We need a good implement. As much as possible, they should not depend
|
||||
upon AC_EMXOS2 etc.
|

|
||||
** More tests
|

Check that AC_REQUIRE circular dependencies are caught.
