It looks like a lot of these warnings are bogus. For example ct_validation is
only ever set to 0 or 1 yet it throws out a warning with if(ct_vlidation) in
one place while not warning about a similar expression just above it.
I tidied up ocsp_prn.c which avoided the warning in that file: though
$ ./config -Wstrict-overflow
...
$ make
...
crypto/asn1/a_strex.c: In function ‘do_print_ex.constprop.3’:
crypto/asn1/a_strex.c:385:12: warning: assuming signed overflow does
not occur when simplifying conditional to constant [-Wstrict-overflow]
if (len < 0)
