       config - User configuration A number of macros is provided for user
       configuration. Defining or undefining such macros triggers variations in
       some library functionality.

       Under a Linux/Unix system, they are (un)set by configure; run

       ./configure --help

        for a list of corresponding command-line options.

       Under a Windows system, they must be (un)defined by editing the file
       <ql/userconfig.hpp> and commenting or uncommenting the relevant lines.

       Such macros include:

       #define QL_ERROR_FUNCTIONS

       If defined, function information is added to the error messages thrown by
       the library. Undefined by default.

       #define QL_ERROR_LINES

        If defined, file and line information is added to the error messages
       thrown by the library. Undefined by default.

       #define QL_ENABLE_TRACING

       If enabled, tracing messages might be emitted by the library depending on
       run-time settings. Enabling this option can degrade performance.
       Undefined by default.

       #define QL_NEGATIVE_RATES

        If defined (the default), negative yield rates are allowed in a few
       places where they used to be forbidden.


        If defined, extra run-time checks are added to a few functions. This can
       prevent their inlining and degrade performance. Undefined by default.

       #define QL_USE_INDEXED_COUPON

        If defined, indexed coupons (see the documentation) are used in floating
       legs. If undefined (the default), par coupons are used.

       #define QL_ENABLE_SESSIONS

        If defined, singletons will return different instances for different
       sessions. You will have to provide and link with the library a
       sessionId() function in namespace QuantLib, returning a different session
       id for each session. Undefined by default.


        If defined, a thread-safe (but less performant) version of the observer
       pattern will be used. You should define it if you want to use QuantLib
       via the SWIG layer within the JVM or .NET eco system or any environment
       with an async garbage collector. Undefined by default.


        Define this to make Singleton initialization thread-safe. Undefined by
       default. Not compatible with multiple sessions.


        If defined, date objects will support an intraday datetime resolution
       down to microseconds. Strickly monotone daycounters (Actual360,
       Actual365Fixed and ActualActual) will take the additional information
       into account and allow for accurate intraday pricing. If disabled (the
       default) the smallest resolution of date objects will be a single day.
       Intraday datetime resolution is experimental.


        Define this to enable the parallel unit test runner. Undefined by
