Compiling tls.c on macoS (17.0/arm) yields the following warnings which I assume are errors:
/opt/projects/prs/g481/src/tcltls-1505883e4a/generic/tls.c:1769:18: warning: variable 'abort' set but not used [-Wunused-but-set-variable]

Fix:
Change the '&&' into '&' since the openssl function returns an int containing a bitmask. I am not converned about the unused variable
abort. I applied this modificationlocally and everything seems to work correctly.
