Run sh -x configure; this generates lots of data on stderr. Identify the failure point somewhere near the end; the text of conftest.c should be above that.

I have performed quite thoroughly in the content of configure file and found no where there is a check for sizeof int, void*, long long etc. My observation is the configure generates a file called conftest.c for each test and then delete it immediately once the test is over. Thus i have no chance looking at the generated content . It comes a little bit worse since i do not know the check point to put some debugging statement.
