[apluslist] FW: A+ compilation errors

[Rui Alberto]

Hi,
I've iostream header in my system. The problem seems to be the way
iostream header presence is checked.
When executing "./configure" the following is reported:
...
checking for new... no
checking for iostream... no
checking for iomanip... no
checking for fstream... no
checking for sstream... no
checking for iosfwd... no
...
and I know that I have iostream header installed in my system,
in: "/usr/include/c++/3.4.2/iostream"

configure.in checks for header existence like this:
AC_LANG(C++)
AC_CHECK_HEADERS(new iostream iomanip fstream sstream iosfwd)

I really don't know nothing about autoconf tools and C++, maybe there's
someone with some experience that could help?!

- A+ version:4.20-1
- gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)

Thanks,

Rui
