The module allways compiles using the version 2 compiler. I have also scoured the code (not a very big source file and can find noplace where they are explicitly setting the compiler version although it is possible i missed it

I expect gcc296 is gcc 2.96. Test this by running:

$/usr/bin/gcc296 -v

You should see something like:

Reading specs from /usr/lib/gcc-lib/i386-redhat-linux7/2.96/specs
gcc version 2.96 200xxxxx

if you have 2.96 (output approximate)

gnatgcc is the ada front-end, and not relevant to your problem.

First try rebuilding your kernel with the gcc296 compiler. If that
    doesn't work, try obtaining 2.95.3 or 2.96 sources.

Finally, firmly but politely tell the vendor they should improve their
