More experiments show that you can set your data segment size soft
limit higher and thereby get through compilation of sha_dgst.c.

On some Alpha installations running True64 Unix and Compaq C, the compilation of crypto/sha/sha_dgst.c fails with the message 'Fatal: Insufficient virtual -memory to continue compilation.' As far as the tests have shown, this is a -compiler bug. What happens is that it eats up resident memory (not the swap) -until the current limit is reached and then dies with the error message given -above. The bug in question is clearly in the optimization code, because if -one eliminates optimization completely (-O0), the compilation goes through -(and the compiler consumes about 2MB of resident memory instead of 128MB or -whatever one's limit is currently).
