This is 6.5.svn:

[neteler at localhost grass65]$ grep _spawnl
*/*/*.cgeneral/g.parser/main.c:        /* execlp() and _spawnlp (
_P_OVERLAY,..) do not work, they return
general/g.parser/main.c:        /* _spawnlp ( _P_OVERLAY, "sh", "sh",
filename, "@ARGS_PARSED@", NULL ); */
general/g.parser/main.c:            _spawnlp(_P_WAIT, shell, shell,
filename, "@ARGS_PARSED@", NULL);
general/g.parser/main.c:            perror("_spawnlp() failed");
lib/gis/system.c:    _spawnlp(P_WAIT, "cmd.exe", "cmd.exe", "/c",
command, NULL);

[neteler at localhost grass65]$ grep _spawnl */*/*/*.c
lib/db/dbmi_client/start.c:     *          otherwise _spawnl fails.
The name used as _spawnl
lib/db/dbmi_client/start.c:    pid = _spawnl(_P_NOWAIT, startup, startup, NULL);
lib/db/dbmi_client/start.c:     db_syserror("can't _spawnl");

> the same procedure with grass64svn delivered with osgeo4w-stack there no such error message and the attribute-table can be opened.

but it seems to be identical to 6.4.svn (the grass64svn delivered with
the osgeo4w-stack is older, though):

[neteler at localhost grass64]$ grep _spawnl */*/*.c
general/g.parser/main.c:        /* execlp() and _spawnlp (
_P_OVERLAY,..) do not work, they return
general/g.parser/main.c:        /* _spawnlp ( _P_OVERLAY, "sh", "sh",
filename, "@ARGS_PARSED@", NULL ); */
general/g.parser/main.c:            _spawnlp(_P_WAIT, shell, shell,
filename, "@ARGS_PARSED@", NULL);
general/g.parser/main.c:            perror("_spawnlp() failed");
lib/gis/system.c:    _spawnlp(P_WAIT, "cmd.exe", "cmd.exe", "/c",
command, NULL);

[neteler at localhost grass64]$ grep _spawnl */*/*/*.c
lib/db/dbmi_client/start.c:     *          otherwise _spawnl fails.
The name used as _spawnl
lib/db/dbmi_client/start.c:    pid = _spawnl(_P_NOWAIT, startup, startup, NULL);
lib/db/dbmi_client/start.c:     db_syserror("can't _spawnl");

Please consider to submit this a ticket if no quick solution is found.
