Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

Because of C language weirdness, the data-type specifier (which normally
goes in at the very left end) may have to be slipped in just to the
right of any leading "const" or "volatile" qualifiers (there may be more
than one). Actually this may not be strictly necessary because it seems
that GCC (at least) accepts `<data-type> const foo;' and treats it the
same as `const <data-type> foo;' but people are accustomed to seeing
`const char *foo;' and *not* `char const *foo;' so we try to create types

parameters list.
New style prototyped ANSI formal parameter lists should in theory always
contain some stuff between the opening and closing parens, even if it is
only "void".
The brutal truth though is that there is lots of old K&R code out there
which contains declarations of "pointer-to-function" parameters and
these almost never have fully specified formal parameter lists associated
with them. That is, the pointer-to-function parameters are declared
with just empty parameter lists.
In cases such as these, protoize should really insert *something* into
the vacant parameter lists, but what? It has no basis on which to insert
anything in particular.
Here, we make life easy for protoize by trying to distinguish between
K&R empty parameter lists and new-style prototyped parameter lists
that actually contain "void". In the latter case we (obviously) want
to output the "void" verbatim, and that what we do. In the former case,
we do our best to give protoize something nice to insert.
This "something nice" should be something that is still valid (when
re-compiled) but something that can clearly indicate to the user that
more typing information (for the parameter list) should be added (by
hand) at some convenient moment.

/* Generate a string which is the source code form for a given type (t). This
routine is ugly and complex because the C syntax for declarations is ugly
and complex. This routine is straightforward so long as *no* pointer types,
array types, or function types are involved.
In the simple cases, this routine will return the (string) value which was
passed in as the "ret_val" argument. Usually, this starts out either as an
empty string, or as the name of the declared item (i.e. the formal function
parameter variable).
This routine will also return with the global variable "data_type" set to
some string value which is the "basic" data-type of the given complete type.
This "data_type" string can be concatenated onto the front of the returned
string after this routine returns to its caller.
In complicated cases involving pointer types, array types, or function
types, the C declaration syntax requires an "inside out" approach, i.e. if
you have a type which is a "pointer-to-function" type, you need to handle
the "pointer" part first, but it also has to be "innermost" (relative to
the declaration stuff for the "function" type). Thus, is this case, you
must prepend a "(*" and append a ")" to the name of the item (i.e. formal
variable). Then you must append and prepend the other info for the
"function type" part of the overall type.
To handle the "innermost precedence" rules of complicated C declarators, we
do the following (in this routine). The input parameter called "ret_val"
is treated as a "seed". Each time gen_type is called (perhaps recursively)
some additional strings may be appended or prepended (or both) to the "seed"
string. If yet another (lower) level of the GCC tree exists for the given
type (as in the case of a pointer type, an array type, or a function type)
then the (wrapped) seed is passed to a (recursive) invocation of gen_type()
this recursive invocation may again "wrap" the (new) seed with yet more
declarator stuff, by appending, prepending (or both). By the time the
recursion bottoms out, the "seed value" at that point will have a value
which is (almost) the complete source version of the declarator (except
for the data_type info). Thus, this deepest "seed" value is simply passed
back up through all of the recursive calls until it is given (as the return
value) to the initial caller of the gen_type() routine. All that remains
to do at this point is for the initial caller to prepend the "data_type"
string onto the returned "seed". */
