Description Daniel Smith 2008-12-18 07:16:35 UTC 
Version: 2.8~20080505-0ubuntu7

warning: ignoring return value of 'strtol', declared with attribute
warn_unused_result

strtol has useful side-effects that do not require examination of the result. 
For example, (void)strtol(string,&string,0) will skip an unneeded number in string.

Suggest warn_unused_result is not applied to strtol and family.
Comment 1 Ulrich Drepper 2008-12-25 18:11:08 UTC 
There are always idiotic code sequences.  For those case work around the warning.
