Hi, as macOS uses clang, I also tried to compile tcc with clang on RPi but a
test fails as below
jullien@sims4:~/tinycc-ba8980f $ ./configure --cc=clang; make && make test
.

On macOS, it now fails for another reason:

It appears that clock_nanosleep is not defined on macOS (at least Catalina):
$ find /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include -type
f -exec grep clock_nanosleep {} \; -a -print
$
This issue does not exist if ./configure incorrectly detects cc=gcc 4.2 (as
with original Michael macos version) while it is in fact cc=clang 11.0 as
correctly detected now.
test2/Makefile has been changed to handle this.
