Yes it's nothing new. You need to know a bit more about Windows than just 
how to point and click to be able to get the most out of GRASS I 
suppose---we're moving away from that obviously - but it still helps.

ISTR around this time last year when we were fixing a lot of tedious 
little things to improve Windows compatibility, having to change commands 
run with system() or similar from within C programs to use double instead 
of single quotes was quite a common problem. Hopefully most occurences 
within C programs have been caught now but perhaps there are still some in 
gis.m?
