global 5.6.1 failed to read GTAGS

[Gregor Beck]

Hi,

global version 5.6.1 failed to read GTAGS generated with gtags version 5.6.1 
for the C-Source of ngspice (http://sourceforge.net/projects/ngspice/)

src> gtags --version
gtags - GNU GLOBAL 5.6.1

src> global --version
global - GNU GLOBAL 5.6.1

src> gtags
src> global DEVices
global: GTAGS seems older format. Please remake tag files.
src> 

Does work with global 4.8.6

Regards

Gregor
