Hello,

% gcc --version gcc (Debian 10.2.1-6) 10.2.1 20210110

Editing the source code so that the #if statement is always true enables successful compilation. If gcc is at fault here, maybe we should report a bug upstream instead of just working around the problem?

gcc 8.5 to 10.2 are no longer supported releases, would not assume that someone from upstream digs into for such issue: https://gcc.gnu.org/ 4.3.0 was tested against: EL7: gcc 4.8.5 EL8: gcc 8.5.0 -> only one having problems EL9: gcc 11.5.0 EL10: gcc 14.2.1 F39: gcc 13.3.1 F40: gcc 14.2.1 F41: gcc 14.2.1 F42: gcc 15.0.1 It was also tested against the "clang" version of the OS versions above, they did not report any issue.

Running tests gives me one error:

You have to install an additional Perl module named Digest::SHA1 Hope this helps, Peter
