warning while compiling/installing Gnu Emacs

warning while compiling/installing Gnu Emacs

[jorge]

Hi,
I've  just compiled and installed Emacs in Linux, but in the process I got 
the following warning, for some functions:
"comparison is always true due to limited range of data type"
Does this mean, that i need to go to every function the warning points to, 
and try tyo fix the types?
The Emacs installation was a success, maybe I just could ignore the warning?

Thanks in advance

There are always warnings.  Sometimes a huge number depending on the
compiler you use and the target system.  Generally they are all
ignorable.  If it was a bootstrap build and was successful and the
object actually runs there is probably nothing to worry about.
I generally get several thousand warnings but it runs great when done.

However, when in doubt, please send the messages and the relevant
compiler information to bug-gnu-emacs@gnu.org.  There's always a
chance that there might be a bug.
