Yes, I did understand that. What I do not understand is the problem with
long long int. On an alpha the normal long int should be sufficient for
storing int8.

This abort() is used to make sure ecpg stops if a type id is found that does
not exist. Normally this must not happen. Ah, now I understand, the parser
accepts long long but typename.c does not like that.

It should be sufficient to just remove the #ifdef in typename.c since
nothing serious is happening there. The reason for this precompiler define
is to make sure that no long long code is generated that the C compiler
cannot cope with. But in typename.c there is no code generated other than
the creation of a string.

Could you please try to just remove the cpp flag? Also I wonder why you are
using "long long int" instead of just "long int" in your C program. Well
that is the people who complained to you.

I thought "long int" is 64 bits too, so that should be sufficient.

Thanks to Tom btw for setting this straight.

I think you were pretty clear from teh get go, but I simply misunderstood
you.
