[GRASS5] d.vect: new segfault

[Florian Goessmann]

markus

it seems to me, that gcc 2.95 simple won't accept any declaration after  
the first control sequence call, thus doesn't work with my patch of  
d.vect.
as debian and osx both work with the changes you applied, i don't have  
any non-working platform.
i'm as lost as you, sorry.

regards
florian

PS: how do you get gdb working? when i want to use it, it complains  
about not finding debugging flags although i compiled with -g and  
-ggdb.
