Hi, 

So what is the fix for this?  Is it to remove the inline keyword or remove 
the typedef? 

Does anyone have a working gnupg on hpux 11.11? 

Thanks

Good catch there.  I think it would be good to report this to the
autoconf people (cc'd).  They can then improve the "inline" testing
code to catch this case, and all autoconfed software can benefit. 

For the autoconf folks: GnuPG uses autoconf 2.54.
