Using a separate script fixes a variety of problems, including establishing

with the way newvers.sh uses `realpath $0`, because $0 expands differently
within a script sourced into a rule in a makefile depending on the version
of make and of /bin/sh being used. The latter can cause build breakage in a
cross-build environment, and can also make it difficult to compile 10.0 on

It turns out that in C++11, char16_t and char32_t are built-in types;
language keywords. Just fix this by putting traditional _*_T_DECLARED
blocks around the definitions. We'll just predefine these in
<sys/_types.h>.
This also opens up the possibility to define char16_t in other header
files, if ever needed (e.g. if we would gain a <ctype.h> for
char16_t/char32_t).
The <uchar.h> header, part of C11, adds a small number of utility
functions for 16/32-bit "universal" characters, which may or may not be
UTF-16/32. As our wchar_t is already ISO 10646, simply add light-weight

I was thinking by myself, if the new code doesn't work with GCC 4.2, why
not simply turn it into an efficient version for C11 compilers? By
changing the code to use _Generic() directly in that case, I can build
the tgmath regression test in a matter of milliseconds with Clang,
instead of the 8 seconds it used to take.
So by the time C11 becomes the default, it will pick up the new code
automatically. And now I will refrain from making more changes to
<tgmath.h>.
Instead of using an exponential number of cases with respect to the
number of arguments, this version only uses a linear number.
Unfortunately, it works with Clang, GCC 4.6 and GCC 4.7, but not GCC
4.2. Therefore, leave it commented out.
It turns out our GCC has quite an interesting bug:
typeof(1.0fi) != float _Complex
typeof((float _Complex)1.0fi) != float _Complex
typeof((float _Complex)1.0i) == float _Complex
In other words: if casting to an equal size, GCC seems to take a
shortcut. By casting down from a double to a float, GCC doesn't take
this shortcut, yielding the proper type.
To prevent foot-shooting, add a _Static_assert() to guarantee that
_Complex_I is always a float _Complex. I'm not going to MFC this part of

There is no way one could possibly use this header file in combination
with C++ code. The problem is that in C11 the `noreturn' macro expands
to the `_Noreturn' function specifier, while in C++11 the `noreturn'
keyword is an attribute.
So in C11 you have to write:
noreturn void exit(int status);
While in C++11 you have to write:
[[noreturn]] void exit(int status);
It is impossible to #define noreturn for C++ in such a way that it
allows both conventions.
By intentionally breaking this header this way, we prevent people from
using this header in their C++<11 sources.
The development version of GCC also supports an atomics interface
similar to Clang's. Change the header file to work as follows:
- __CLANG_ATOMICS: Use Clang's new atomics interface,
- __GNUC_ATOMICS: Use GCC's new atomics interface,
- else: fall back to GCC's __sync interface.
Even though _Static_assert() is pretty robust for C code, it cannot work
correctly with C++ code. This is due to the fact that C++ template
parameters may contain commas that are not enclosed in parentheses. For
example:
static_assert(foo<int, int>::bar == baz, "...");
This causes _Static_assert to be called with an excessive number of
parameters. If you want to use static_assert in C++, just use a C++11
compiler.
