The compilers gcc-5.1 and cilkplus-4_8-branch were bootstrapped using the
Debian 4.7.2-5 gcc compiler on Debian Wheezy. Compiling and running the test
program yields the following output:

To check the installed version of iconv has C99 support type
$ iconv --list | grep "C99"
C99
$
which means that iconv is recent enough.

GCC version 5.2 has come around and the bug is still here.
In particular, compiling for 32-bit Intel or using -mfpmath=387 in 64-bit leads
to immediate floating point exceptions. The fix was to comment out the defin

Please look at the Raspberry Pi forum post linked in the original report for

I'm glad to know people like Joseph are working on UTF-8 in gcc. Last year I
spent a week adding UTF-8 input support to pcc. At that time Microsoft Studio
and clang already supported UTF-8 input files and I expecte

While there may not be current demand for gcc to accept UTF-8 identifiers, the
fact that clang and Visual Studio support this C99 feature means source code
using Greek and accented characters in variable names is lik

With my second patch the command line must now include the options
-finput-charset=UTF-8 -fextended-identifiers -fexec-charset=UTF-8
or otherwise C99 will also be used for the default execution character set.

Thanks Joseph for the clarification about the two different versions of iconv.
I was admittedly confused about this until moments ago. Anyway, I just
discovered that libiconv doesn't support conversions to and from

I've been looking at the code in lex_identifier as well as what goes on in
forms_identifier_p and so forth. As some point each identifier needs to be
stored in the symbol table using ht_lookup_with_hash. Proper fun
