While building the package using our research compiler infrastructure we noticed
the following conflicting declarations of variables alfa, beta and gama (sic!):

(with tex.c: typedef unsigned long dword;)

./tex.c:64:dword alfa, beta, gama;
./tex.h:31:extern int alfa,beta,gama,centerx,centery,centerz;

The difference in signedness and size (on architectures with
sizeof(long)!=sizeof(int)) will cause undefined behaviour, in particular on big
endian systems.

Best,
Michael

Hi Michael,

Do you by chance can tell me, on which architectures I at least should
test a potential fix, e.g. for crashes?
