* aclang.m4 (_AC_LANG_COMPILER_WORKS): Rename as...
(_AC_COMPILER_EXEEXT_WORKS): this. Use the `a.out' or `a.exe' left by _AC_COMPILER_EXEEXT_DEFAULT to check if the compiler works. (_AC_COMPILER_EXEEXT_CROSS): Extract from the above macro. (_AC_COMPILER_EXEEXT): Use them. Adjust all the compiler looking macros to check for EXEEXT *first*, then OBJEXT. Set ac_exeext yourself. (_AC_COMPILER_EXEEXT_O): Don't.

* Serious Problems
|

|

** Broken compilers
|
||||
|
||||
configure does not properly diagnose broken compilers (because it
|
||||
finds the failure before the code that checks whether the compiler
|
||||
works). It is not to serious a bug, but most notably the test suite
|
||||
will fail to handle gracefully missing compilers (typically the
|
||||
Fortran compiler).

** Special characters and config.hin
