A shared connection cache is not thread-safe is a known issue. Stop
testing this until we believe this issue is addressed. Reduces
occasional test failures we don't care about.
The test code in lib1541.c is left in git to allow us to restore it when
we get to fix this.
Closes#5922
The threaded-shared-conn.c example turned into test case. Only works if
pthread was detected.
An attempt to detect future regressions such as e3a53e3efbCloses#3687
system.h is aimed to replace curlbuild.h at a later point in time when
we feel confident system.h works sufficiently well.
curl/system.h is currently used in parallel with curl/curlbuild.h
curl/system.h determines a data sizes, data types and include file
status based on available preprocessor defines instead of getting
generated at build-time. This, in order to avoid relying on a build-time
generated file that makes it complicated to do 32 and 64 bit bields from
the same installed set of headers.
Test 1541 verifies that system.h comes to the same conclusion that
curlbuild.h offers.
Closes#1373
