Subject: Fixes for NonStop builds on 3.4 to handle OS platform header file changes
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b1ef2f1ff096e14621f98bbb551c383c867a5bc9;p=thirdparty%2Fopenssl.git

Fixes for NonStop builds on 3.4 to handle OS platform header file changes

This changes handles the introduction of _POSIX_VERSION into the NonStop x86
header files that tricks OpenSSL into thinking that ucontext.h is available.

Build a workaround in timing_load_creds.c on NonStop for lack of rusage.
This simulates getrusage() that is not available on NonStop.

Fixes #28498
Fixes #29023
