I understand that and it makes sense but right now I'm stuck with alot of
code that could take days to fix. Unfortunatly it's not a 2 minute patch in
my case since the code in question will also affect lots of other platforms
that I support. This requires alot of testing.

__asm__("ta 6");

at the beginning of main will workaround all your issues, albeit slowly.

I have a file which gets read into malloced memory. Then do a trick like:

if (((struct a*) m_ptr)->some_member == MAGIC_VAL)

Ah, you have a file based data structure. This too will explode.

Code like above probably will not work anymore, right? So in this case I
need to have extra temporary variables to extract the values in question. In
this case the value would be a 32 bit integer stored in an endian neutral
way, but it could also be any other primitive datatype or even an array. I
am not really sure how to go through all these cases since it takes quite a
bit of time to *think* about if a specific piece of code could be a problem
or not.

Quite; or you could have functions which extract integers at certain
locations.
