AC_CPLUSPLUS doesn't work

[Stefan Seefeld]

hi there,

I'v run into another problem with autoconf 2.52:

at some point, I set the language to be used to C++,
as I code in C++ and want all tests to be performed
with C++.

However, the language is automagically set back to C
before the actual tests are performed, such that some
tests fail. I browsed the generated configure file
(*shudder*), and it appears that AC_LANG had indeed
been called quite a couple of times after I called

AC_LANG_CPLUSPLUS.

(by the way, adding comments to each macro in the
 generated output ('configure') would really help
 to make the whole more intelligible !)

Any help would be highly appreciated. For example:
what macros call AC_LANG themselfs ? Should there
be *any* macro calling this ? I thought this kinda
defeats the whole purpose of that feature...

Regards,
                Stefan
