Subject: test/bioprinttest.c: skip failing checks on HPE NonStop
X-Git-Tag: 4.0-PRE-CLANG-FORMAT-WEBKIT~107
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=edc8edb9579ac1219df302529f986e5ddf755d24;p=thirdparty%2Fopenssl.git

test/bioprinttest.c: skip failing checks on HPE NonStop

Apparently, NonStop libc's printf implementation is not
standard-conforming in its handling of "0" flag with "o" specifier:
per [1], "it shall increase the precision, if and only if necessary,
to force the first digit of the result to be a zero", however, NonStop
libc adds a superfluous zero in cases where precision is 1;  see also
commit 0f107c709c73 "crypto/bio/bio_print.c: avoid superfluous zero
padding in %#o".  Avoid test case failures by wrapping the relevant test
cases in "if !defined(__TANDEM)".
