http://stackoverflow.com – I encountered the following warning from gcc 4.1.2: warning: comparison is always false due to limited range of data type the concerned C code is like: if ( unlikely(count < 0) ) BUG(); where 'count' is unsigned. I tried to disable the warning since I was not allowed to modify the source code: -Wno-type-limits but it seems gdb 4.1.2 does not support it. cc1: error: unrecognized command line option "-Wno-type-limits" Any other ways to get rid of this warning?

I am using gcc 4.1.2 on Linux, and I encountered the following warning:

warning: type qualifiers ignored on function return type

I tried to use "-Wno-ignored-qualifiers" to get rid of this warning but it seems not supported:

cc1: error: unrecognized command line option "-Wno-ignored-qualifiers"

Is there a way to disable such warnings in gcc 4.1.2?

Thanks a lot.
