Please gzip the output of 'configure' and o= f=20 'make' and the contents of 'config.log', and attach the resulting file. I assume Intel's does not define max_align_t as C11 requires; = is that=20 right? If so, the 'configure' command is supposed to arrange for lib/stdd= ef.h to=20 define max_align_t. Apparently this is not working for you. Does 'make' build a file lib/stdd= ef.h at=20 all? If not, why not? If so, what does lib/stddef.h contain?
