Ubuntu 22.04LTS - compilation error using crypto++

Hi,

I'm trying to compile an old project using crypto++ under Ubuntu 22.04LTS 
with libcrypto++ version 8.6. Compiler is clang 14

I get an "use of undeclared identifier bswap_32, did you mean __bswap_32 ?

When browsing the source, I find in misc.h:

#if defined(CRYPTOPP_BYTESWAP_AVAILABLE) 
    return bswap_32(value);
...

When browsing the source, everything looks fine. Preprocessor directives 
detect clang, include <byteswap.h> which in turn includes 
<bits/byteswap.h>. The latter defines a __bswap_32 function, and the first 
#defines bswap_32(x) as __bswap32(x).

So I have no clue why compiling fails. Has anyone encountered the problem?
