* harbour/source/vm/thread.c
+ added small description for hb_threadOnce() .prg function
* harbour/include/hbthread.h
! do not set TLS in POCC and XCC builds when _MSC_VER macro is set
This compilers also have this macro but dllspec( thread) does
not work for them (at least in version 4.50.15)
* harbour/utils/hbtest/rt_hvm.prg
+ added few tests which exploit by DMC bug. Be careful with
this compiler. In some cases it gives buggy final code, f.e.
try this:
#include <stdio.h>
typedef struct
{
double dd;
long long int ll;
} UN;
const char * cmp( UN * pU )
{
return pU->dd >= pU->ll ? "OK" : "ERRROR";
}
int main( void )
{
UN u = { 10.50, 10 };
printf( "%s\n", cmp( &u ) );
return 0;
}
The same bug can be exploited also by final Harbour binaries
compiled by DMC in code like:
? iif( 10.50 >= 10, "OK", "ERROR" )
I used DMC 8.42n. As long as such things will not be fixed by
DMC developers this compiler is not supported by Harbour and
reported problems with DMC Harbour builds will have to be
ignored by us.
