description "
The math library can be hard-coded to only
behave in one compatibility mode - IEEE. This
cannot be changed at run-time. IEEE mode is the
most minimal of the compatibility modes, and so
this will best help code size and speed, as well
as omitting the code for other compatibility
modes. If not defined, the math library can be
set at run-time to any of the supported
compatibility modes."

If you want to have support for more than one
compatibility mode settable at run-time, rather

you choose which mode should be the default."

This option automatically defines the default compatibility

to set that mode at run-time."

cdl_option CYGFUN_LIBM_SVID3_scalb {
display "SVID3-style scalb()"

description "
SVID3 defined the scalb() function as double
scalb(double, double) rather than double
scalb(double, int) which is used by IBM, DEC, and
probably others. Enabling this option chooses
the (double, double) version. Note there is a
function double scalbn(double, int) which is
unaffected by this choice."
}
 
cdl_option CYGSYM_LIBM_NO_XOPEN_SVID_NAMESPACE_POLLUTION {
display "Reduce namespace pollution"
default_value 0
description "
If you do not want to use either the X/Open or
SVID3 compatibility modes, you may want to define
this option to reduce the chance of namespace
pollution. This is particularly likely to occur
here as these standards define symbols with
names that often appear in applications, such as
exception, DOMAIN, OVERFLOW, etc. If your
application also used these names, it may cause
problems."

description "
The SVID3 standard says that error
messages should be output on the stderr console
output stream. This option allows this ability
to be explicitly controlled. However, this still
only has an effect in SVID3 compatibility mode."

the absolute value of their argument. The sign
of the argument is stored in a variable called
signgam. Enabling this option makes signgam
a per-thread variable. Note there are also
