Been there; sorry I did not mention it. 'gcc -E' gave me:

 PRUint64   PR_ntohll(PRUint64 n)
{
    PRUint64 tmp;
    PRUint32 hi, lo;
    (( lo ) = (PRUint32)(  n )) ;
    (( tmp ) = (PRInt64)(  n ) >> (  32 )) ;
    (( hi ) = (PRUint32)(  tmp )) ;
    hi = PR_ntohl(hi);
    lo = PR_ntohl(lo);
    (( n ) = (PRInt64)(  hi )) ;
    (( n ) = (PRInt64)(  n ) << (  32 )) ;
    (( tmp ) = (PRInt64)(  lo )) ;
    (( n ) = (  n ) + (  tmp )) ;
    return n;
}

- no eerie inline assembler code here - and 'gcc -S' then died with:

as before. ISTR the gcc version has changed since 1.4?
