Hi, I was unable to compile Tor for powerpc32 for a while but I was unable to bisect it because of other compilation errors (and "git bisect skip" did not help): ----------------------------------------------- CC src/or/scheduler.o In file included from src/or/or.h:91:0, from src/or/scheduler.c:9: src/or/scheduler.c: In function 'scheduler_adjust_queue_size': src/or/scheduler.c:623:18: error: comparison is always true due to limited range of data type [-Werror=type-limits] (dir >= 0) ?

Below is my attempt to fix this issue by declaring "dir" as "signed char". It compiles now (4.6.3 and 4.9.1) for powerpc32 and Tor seems to work - but please have a look if this is the Right Thing To Do. Thanks, Christian. Declare "char dir" as signed, otherwise compilation on powerpc32 would fail with: ------------------------------------- CC src/or/scheduler.o In file included from src/or/or.h:91:0, from src/or/scheduler.c:9: src/or/scheduler.c: In function 'scheduler_adjust_queue_size': src/or/scheduler.c:623:18: error: comparison is always true due to limited range of data type [-Werror=type-limits] (dir >= 0) ?
