X-Git-Tag: 2.42.0~213^2^2~23
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=25fc2bcef8cb565f04081660fc60697d1f863b98;p=graphviz

Modify files generated by Bison and Flex, to match the Autotools build.

- Replace "yy" with "aag" in all three files
- Replace "unsigned long int" with "uint64_t" in grammar.h and grammar.c
- Replace "unsigned long" with "uint64_t" in grammar.h and grammar.c
- Remove declaration of the "isatty()" function from scan.c
