support of C99 VLA in compilers

[Ben Hinkle]

I checked the FAQ but didn't see any mention of C99 support in today's
compilers. In particular I'm interested in VLA support. Any links or info
about the status? I read that GCC had experimental VLA support since before
C99 and that it still isn't exactly the same as the C99 VLA.

thanks,
-Ben

Comeau C/C++ has full C99 support, including VLAs. So does
the latest compiler from Sun, which is now free. Otherwise,
any compiler that uses the EDG front end (such as Comeau)
should support VLAs.

Hunt down the gnu home page for gcc (unsure about URL). They
maintain a page specifying the degree of C99 compliance achieved,
with details.

Googling gcc c99 status yields <http://gcc.gnu.org/c99status.html>.

In case its not on there I can confirm that GCC has supported
VLAS since before gcc-2.95.

However that support does not conform to the C99 standard and GNU have
never claimed that it conformed to the C99 standard.

In the implementation table it's listed as "broken" - out of curiosity,
how does the gcc implementation differ from that in the c99 standard?
