Hmm.  I installed MPLAB X on my Mac (including pic32-gcc 2.01), and there i=
s no symbol _UART4_VECTOR defined anywhere that I can see.

There *is* a _UART_4_VECTOR off in p32mx695f512l.h

And there are _UART1_VECTOR and _UART2_VECTOR in ppic32mx.h:

#define _UART1_VECTOR                            _UART_1_VECTOR
#define _UART2_VECTOR                            _UART_2_VECTOR

(what, won't your windows system do a quick content search of your entire d=
isk, like the Mac's "spotlight" feature?  PShaw!)

There are also a bunch of other _UART4_xxx_IRQ defines that appear to be IR=
Q numbers rather than vector numbers, and have values exceeding 63.  Why th=
e inconsistency?  I dunno!  (cursed HW companies trying to write software!)

So, try:
