Package: ogre
Version: 1.0.6-1.3
Severity: important
Your package fails to build on MIPS with GCC 4.1.
Note that this is not the same as the last bug I filed about GCC 4.1
problems. This one is MIPS specific. I tested the patch I submitted
on AMD64 and it works fine. However, there's another complication on
mips.

Line 609 is:
int mips = -1; // When passed to TextureManager::load, this means default
to default number of mipmaps
Looking at the code generated by GCC shows that it tries to compile:
int 1 = -1;
Further investigation shows that on MIPS the constant "mips" is
defined as 1. I have no idea who thought this was a good idea, but
the compiler does it - so please use a different variable name.
Apparently GCC on i386 defines i386=1 too... *shakes head*
