Module Name: src Committed By: apb Date: Tue Jul 14 21:15:48 UTC 2009
Modified Files: src/usr.bin/mail: lex.c Log Message: Declare "com" as volatile in execute(), to make it safe to use across setjmp/longjmp. Inspired by PR 41255 from Kurt Lidl, but this change makes "com" a volatile pointer to const non-volatile data, whereas the PR made it a non-volatile pointer to const volatile data.
