[Debichem-devel] Bug#462071: FTBFS with GCC 4.3: missing #includes

[Martin Michlmayr]

Package: liboglappth
Version: 0.96-3
Usertags: ftbfs-gcc-4.3

Your package fails to build with GCC 4.3.  Version 4.3 has not been
released yet but I'm building with a snapshot in order to find errors
and give people an advance warning.  In GCC 4.3, the C++ header
dependencies have been cleaned up.  The advantage of this is that
programs will compile faster.  The downside is that you actually
need to directly #include everything you use (but you really should
do this anyway, otherwise your program won't work with any compiler
other than GCC).  There's some more information about this at
http://gcc.gnu.org/gcc-4.3/porting_to.html

You can reproduce this problem with gcc-4.3 or gcc-snapshot from
unstable.
