I see (a) that there is '*/' missing in the first line. And I see (b) a warning
only for line 28 (with '-Wall), which looks odd:
c-c++-common/goacc-gomp/nesting-1.c:28:9: warning: ‘i’ is used uninitialized
[-Wuninitialized]
28 | int i;
| ^
c-c++-common/goacc-gomp/nesting-1.c:28:9: note: ‘i’ was declared here
28 | int i;
| ^
'i' seems to be unused on the host but due to the firstprivate it is read –
while inside the region it is assigned a value 'i = 0'.
But I have only glanced at it.
