Re: Problem with compiling gengetopt on OpenSolaris

Hi Lorenzo,

thanks a lot for both your e-mails.  I just tried the fixed version and 
it compiles on my OpenSolaris box without any problems (I tried again 
both gcc and SunStudio cc).  When do you plan to have this fixed version 
publicly available (gengetopt 2.22.2)?

Thanks,
Lukas
