The default implementation of "GetTickCount" just uses the lower 32-Bit from the result of "GetTickCount64".
The default implementation of "GetTickCount64" is based upon "Now" for systems that support a floating point unit (and thus "Now").
Other systems can define a "SysTimerTick" function which is used instead if "HAS_SYSTIMERTICK" is defined.
The Windows implementation of "GetTickCount" uses Windows' "GetTickCount" function.
The implemenation of "GetTickCount64" checks whether the system is a Windows Vista or newer and then uses Windows' "GetTickCount64" function. Otherwise Windows' "GetTickCount" is used also.
The Unix implementation of "GetTickCount" is the default one.
The "GetTickCount64" implementation uses "fpgettimeofday".

* EExternal.ExceptionRecord changed from field to property and made available on all Windows, not just win32.
* CatchUnhandledException: removed AnsiString variable, ideally there should be no memory allocations in this code path.
git-svn-id: trunk@19849 -
* Some Delphi-compatible changes:
* For floating point underflow condition, raise EUnderflow, not EOverflow.
* For unknown codes, raise EInOutError, not Exception.
* Added entries for EZeroDivide and EStackOverflow (actually raising EZeroDivide on floating-point division by zero requires further changes to System because currently both integer and float division by zero is mapped to the same code 200).

Options now include stripquotes
* Changed ExeSearch so dirlist is optional and PATH is used if omitted.
It uses stripQuotes on windows. (bug 19282)
git-svn-id: trunk@17717 -
* return value of GetLastOSError if one is available, to be consistent with handle-based implementations and Delphi behavior.
* otherwise, return -1

unit's initialization code in case we're in a library
+ implemented InquireSignal(), AbandonSignalHandler(), HookSignal() and
UnhookSignal() in the sysutils unit
* for Kylix compatibility, these routines support operating on
SIGINT and SIGQUIT as well, although they are not hooked by default
by FPC. The run time errors/exception codes for these signals are
resp. 217 and 233 (same as in Kylix; I changed ENoWideStringSupport
to 234).
* changed the BSD syscall version of fpsigaction to use pointer
rather than "var" arguments (compatible with other targets, and
required to be able to pass nil arguments inside the system unit)
-> together fixes mantis #12704

- Remove sysutils dependency by turning exception into runerror, which is
converted into exception anyway if user decides to use sysutils.
