Description Alexandre Oliva 2004-09-29 20:57:14 UTC
The <limits> header defines default values for NaN-related booleans
and values, but no machine-specific config file overrides the
defaults, that are not appropriate for say x86.

I realize the implementation in say gcc 3.4 relies on a number of
compiler built-ins (macros and functions) that are probably too much
risk or work to back-port, but we could simply hard-code the correct
definitions for the macros in machine-specific headers for the
platforms we support.

Comment 2 Benjamin Kosnik 2004-10-04 22:36:45 UTC
FYI <limits> re-write took place between 3.2.x and 3.3.x. 

Alexandre's original point, however, that hand-edited bit can get put
in the file on a per-target basis.
