INFO Patch TNT V1.1alpha2
-------------------------

Hello,

TNT V1.1alpha1 did not compile with module-xx-patched 2.0.x-kernels or
2.1.x-kernels and the 2.1.22b-ax25-utilities.

Apply the following patch and you can compile and use TNT. It was tested
with Kernel 2.0.29 with module-12 and ax25-utilities 2.1.22b.

Of course the 'lib'-link in the source directory of TNT must point to the
'lib'-directory of the ax25-utilities 2.1.22b.

Thanks to Jonathan, G4KLX and Joerg, DL1BKE for patches. As Rose and Netrom
support needs some restructuring of the code, support for these will follow
later.

73, Mark
