Without the change I get no output:

G57: > v.out.ascii in=land
writing to stdout
G57: >

same for maps with only areas or maps with only lines.


Changing & to && I get:

G57: > v.out.ascii in=land | wc -l
writing to stdout

Changing to "if ( pnt && !(type & (GV_POINT|GV_CENTROID) ) ) {"
 I get:

G57: > v.build land
Building topology ...

Topology was built.

not sure which is "better" or expected output. Usually I'd think nodes
were more useful to have exact positions for than centroids..
