I changed vbsrecord to look like:
#if !defined(VBS_MAX_LRECL)
#define VBS_MAX_LRECL 32767
#endif
typedef struct {
int vbslrecl;
char vbsdata[VBS_MAX_LRECL]; /*actually this is "vbslrecl" bytes of data */
} vbsrecord ;
which allows the user #include it, but set the maximum lrecl themselves to
some value. If they don't, it will default to 32767. I haven't looked at
changing vbsread() yet.
