Package: g++-4.3
Version: 4.3.1-8
Severity: important


when trying to compile the following file:

   #include <cstddef>

with g++-4.3 (4.2 works fine), I get:

   In file included from x.C:1:
   /localvol/usr/bin/../lib/gcc/../../include/c++/4.3/cstddef:48:25: error: stddef.h: No such file or directory
   In file included from x.C:1:
   /localvol/usr/bin/../lib/gcc/../../include/c++/4.3/cstddef:55: error: '::ptrdiff_t' has not been declared
   /localvol/usr/bin/../lib/gcc/../../include/c++/4.3/cstddef:56: error: '::size_t' has not been declared

the reason is that the incldue file order is broken in g++-4.3, the c includes come first:

   /localvol/usr/bin/../lib/gcc/x86_64-linux-gnu/4.3.1/include
   /localvol/usr/bin/../lib/gcc/x86_64-linux-gnu/4.3.1/include-fixed
   /localvol/usr/bin/../lib/gcc/../../include/c++/4.3
   /localvol/usr/bin/../lib/gcc/../../include/c++/4.3/x86_64-linux-gnu
   /localvol/usr/bin/../lib/gcc/../../include/c++/4.3/backward
   /usr/local/include
   /usr/include

since cstddef is in c++/4.3, g++ is unable to find stddef.h which comes
earlier. Here is the full output from g++-4.3 -v;

My quick guess is that g++-4.3 gets confused because /usr is a symlink to
/localvol/usr, but I can't pinpoint where exactly the problem is. g++-4.2
has no such issues on the same system. Or maybe it's the duplicate path -
I have no clue, but the issue persist for some months now, I only got to
report it now, intiially believeing it was my fault somwehere.
