Comment(by glynn):
Replying to [ticket:2278 neteler]:
> For a better error message, perror() should be used:
Ideally, strerror() (or similar) should be used, and the string included
in the error message. Otherwise, the additional details will be omitted
from any logfile ($GIS_ERROR_LOG) or email message ($GRASS_ERROR_MAIL).
Except, strerror() isn't thread-safe (it returns a pointer to a static
buffer). POSIX.1-2001 specifies strerror_r(), which requires the caller to
supply a buffer. Windows doesn't have that, but it has strerror_s (same
functionality, different argument order). So we'd need configure checks.
