asterisk users - Mar 2004 - Asterix build errors. Bison related...

Hi,

I did the following:
1) Obtained asterisk-0.7.2.tar.gz from digium's website.
2) Extracted to /usr/src/asterisk/
3) Attempted the make command.

I obtained the following errors after quite some time in the build process:

"gcc -pipe  -Wall -Wstrict-prototypes -Wmissing-prototypes

Is it a problem with the version of Bison? can anyone please provide any clues
regarding the problem.

thanks,
