Detect and work around a bug in gcc2.95 which requires that we use some non-ISO C++. While we are at it, require autoconf2.50 or higher, which is what we implicitly required before already.

Work around the following bug in Sun's Forte compiler, by simply
adding a private inheritance of B1. Since that base class only has
static members, that does not hurt anyway.
/* ------------------------------------------------- */
/* Problem 17 -- access control: compiler error */
/* Error: B1::dim is not accessible from B1::X<2>. */
/* Where: While specializing "B1::X<2>" */
/* Where: Specialized in non-template code. */
/* Note that "dim" should actually be placed with */
/* B1::X, rather than with B1. */
template <typename T> class V {};
struct B1 {
template <int dim> struct X {
int i[dim];
};

struct B2 : private B1 {};
struct D : public B2, private B1 {
~D () {};

Work around a bug in Sun's Forte compiler. The code in question was
dangerous anyway, and since this is no performance critical place, we
take the plunge.

Detect and work around the following bug in pre-3.0 gccs:
struct X
{
template <typename T2>
X operator = (T2 &) {return *this;};
};
template X X::operator=<> (float &);
These compilers reported
x.cc:7: 'operator =' not defined
x.cc:7: confused by earlier errors, bailing out
and wanted that we write
template X X::template operator=<> (float &);
instead. This is not what the standard prescribes, and is also not necessary for regular member functions.
Unfortunately, we cannot simply add that 'template' here, since otherwise Sun's Forte compiler no more
groks this. So we define a symbol DEAL_II_MEMBER_OP_TEMPLATE_INST which is empty for standards
compliant compilers, or 'template' in case of broken gcc's.

Work around a really ugly bug in Suns Forte compiler, which manifests itself at the following testcase:

When we forward declare the general Tensor template, also declare that it has a partial specialization. Otherwise, Sun Forte is confused, but I believe rightfully so. Unfortunately, its error messages are less than helpful in this case...

Significantly change the way configure works. Mostly, configure.in is now only a list of task to be done, cleanly separated into several categories. The actual work is done by macros in aclocal.m4. Also, config.guess and alike have been banned from the top-level directory and are now in contrib/config.
