The PLATFORM_IDENTIFY macro matches the output of Tcl's platform::identify
and is meant to permit extensions to pick a platform-specific directory for
binaries.
MULTIPLATFORM_INSTALL can be set by extensions to install into a platform
specific subdirectory as returned by the platform::identify Tcl command.
The default automatic pkgIndex.tcl is modified accordingly.
If OPTS=pdbs is set, the default install target will also copy PDBS.

NRT-capable):
- the clock ticks never backwards (avoid it by negative drifts using comparison of times before and after calibration);
- more precise, smooth/soft drifting (avoids too large drifts, already after 10 iterations the drift gets fewer as 0.1 microseconds);
- because of more accurate drifting (aspire to the smallest difference), we can prolong calibration interval (up to 10 seconds by small tdiff-value);

Do gcc-compiles with the option -Wwrite-strings, so we can detect mis-usage of "const".

denominator scale to/from microseconds, and therefore more precise "timerate" results under windows (using similar mechanisms as by Mac OSX).
Especially multi-threaded, because it works without lock opposite to microseconds (that use crictical section, because of the calibration thread).
The reason for usage of wide clicks instead microseconds explains following example (shows 20% performance deference):
% timerate -calibrate {}
% timerate {clock microseconds} 5000
0.297037 µs/# 14465901 # 3366585 #/sec 4296.906 nett-ms
% timerate {clock clicks} 5000
0.247797 µs/# 16869084 # 4035554 #/sec 4180.116 nett-ms

high resolution clicks are not microseconds based;
[win] use high resolution timer for the wide clicks and microseconds directly, prevent several forwards/backwards conversions;
[win, unix, mac-osx] normalize some functions for common usage in different time units (clicks, micro- and nanoseconds)
