annotate rogue5/state.c @ 231:455464db5800

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Don't force the use of GCC. Due to incomplete autoconfiscation, most of the Makefiles ignored the C compiler found by 'configure' and always used 'gcc'.
