Change (back) to address type being signed.
DIV and MOD fully defined for the full range of integer on both parameters.
_X, _XF, _R and _RF checks upgraded for 64 bit support.
ASH upgraded for 64 bit.
Add div and mod tests to language confidence test.
Enable debuggable C compiler options.
* Deduplicate common constants into OPM and do some source format tidying.
* Fix postpush buildall script to force checkout of updated buildall.
* Show enlistment branch in makefiles
* Support non-printables in string literals and tidy case alignment and constant literals.
* Common code for MIN and MAX of integer types.
* Common code for SInt/Int/LInt in ConstOp parameter preparation.
* Common code for SInt/Int/LInt in Op parameter preparation.
* Refactor SetIntType to work with byte size directly. Prepare to revert my incorrect VAL changes.
* Original meaning of VAL restored. Many library files disabled until use of VAL in 64 bits fixed.
* Make Reals.Mod independent of INTEGER size and add reals tests.
* Implement fraction, IsInfinity and IsNaN in oocLowReal.Mod.
* OPB little simplifications and ShorterSize/LongerSize functions.
* Add test for alignment computability
* Replace alignment constants with calculated alignment.
* typ.size aware OPV.Convert
* Add SYSTEM_INT64 and make tests name independent.
* Remove SYSTEM.H includes (string.h and stdint.h).
* Replace uses of uintptr_t and size_t with SYSTEM_ADDRESS.
* Sad hack to make FreeBSD and OpenBSD happy with memcpy declaration.
* Detect 64 bit on FreeBSD, and size_t defined on OpenBSD.
* %zd not supportd by mingw, cast strnlen return to int.
* Add debug for intermittent failure only on OpenBSD.
* Add textTexts as a confidence test and tidy up a couple of other tests.
* Update binary test process.
