Subject: Remove the dependency of gram .h on gram.y, the .c dependency is enough.
X-Git-Tag: SUDO_1_7_0~399
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0e30ec1997b81b50a5e4c7deebe694845ea82256;p=sudo

Remove the dependency of gram .h on gram.y, the .c dependency is enough.
Only move y.tab.h to gram.h if it is different; avoids needless rebuilding.
