I've seen the later messages about DECC not being the same as VAX C,
but just for completion, here are the list of RTLs from VAX/VMS 4.6:

$ dir sys$library:*rtl*

Directory SYS$SYSROOT:[SYSLIB]

ADARTL.EXE;1        BASRTL.EXE;1        BASRTL2.EXE;1       COBRTL.EXE;1       
FORRTL.EXE;1        LIBRTL.EXE;1        LIBRTL2.EXE;1       MTHRTL.EXE;1       
PASRTL.EXE;1        PLIRTL.EXE;1        RPGRTL.EXE;1        SCNRTL.EXE;1       
UVMTHRTL.EXE;1      VAXCRTL.EXE;2       VAXCRTL.JNL;1       VAXCRTL.OLB;1      
VAXCRTLG.EXE;2      VAXCRTLG.JNL;1      VAXCRTLG.OLB;1      VMSRTL.EXE;1       

Total of 20 files.

And here is the same list from VAX/VMS V4.0:

$ dir sys$library:*rtl*

Directory SYS$SYSROOT:[SYSLIB]

BASRTL.EXE;1        BASRTL2.EXE;1       COBRTL.EXE;1        FORRTL.EXE;1       
LIBRTL.EXE;1        LIBRTL2.EXE;1       MTHRTL.EXE;1        PASRTL.EXE;1       
PLIRTL.EXE;1        RPGRTL.EXE;1        VMSRTL.EXE;1        

Total of 11 files.

And finally, the same list from VAX/VMS V3.7:

$ dir sys$library:*rtl*

Directory SYS$SYSROOT:[SYSLIB]

PASRTL.EXE;1        PLIRTL.EXE;3        RTLVECTOR.OBJ;1     VMSRTL.EXE;3

Total of 4 files.
