annotate rogue5/mach_dep.c @ 239:837044d2c362

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Merge the GCC5 and build fix branches. This fixes all warnings produced by GCC 5, except the ones related to system functions. Those could be fixed by including the proper headers, but it would be better to replace the system-dependent code with functions from mdport.c.
