Haven't looked at the GNU Sather code recently, but I have a version
that (intentionally) spews a lot of warnings, and I usually compile
with -C_flag -w.  You can do that and not be disturbed.

My runtime.sa doesn't seem to have this issue.  This by esc is all that
mentions isnormal

-------------------------------------------------------------
    161 #ifdef linux
    162 # define FLTDEXP10(f)    pow10(f)
    163 #define iszero(f) ((f)==0.0)
    164 #ifndef isnormal
    165 # define isnormal(f) ((int)1)  /* these two are hacks esc*/
    166 #endif
... #endif

---------------------------------------------------------------

It's only defined if undefined.

The general story with C compiler warnings, I think, is that the
Sather compiler wants to jump through a few hoops and do a lot of
things that if we were application programming in C would be
deprecated, but we're not.  But they are worth turning on and looking
at, keeping in mind that they're there in case you notice ways of
removing one or two.

My Compiler/cs.module looks like this:

-----------------------------------------------------------
Abstract_Syntax/Abstract_Syntax.module
Front/Front.module
Middle/Middle.module
Back/Back.module
Abstract_Machine/Abstract_Machine.module
Configuration/Configuration.module
Representation/Representation.module
--pSather/pSather.module -- ptrans.sa has been moved into trans.sa

-has tuner.sa TUNER
-- -C_flag -w
-C_flag -Wall
-C_flag -Wno-unused-variable
-C_flag -Wextra
-C_flag -Wno-ignored-qualifiers
-C_flag -Wno-uninitialized
-C_flag -Wno-unused-parameter
-verbose
cs.sa
---------------------------------------------------------------

For "cs" you have something else in GNU Sather.
