Hi list, (gdb) whatis Prioritee_trouvee type = <invalid type code 19> 183$ gpc --version 971001(2.7.2.1) Prioritee_trouvee (found_priority) is defined as a Boolean. If evaluated, gdb will give it a value of 8, and this invalid type code 19! What's 19 for GPC? Also, how many Peter Gerwinsky are there over there? I just cannot believe they are only one always behind the computer solving all those problems, answering all those questions, all the time, all the time! Can we copy them as part of the GNU project? (no offense of course) Cheers. F.P.L
