A bit tricky here. You need to use the C30 toolsuite instead of ASM30.

Here's what I needed to do to solve my problem (assuming you are
assembling your project within MPLAB IDE 7.52 or later).
(Note: I did not have to change or add anything special to the command
line options).

1) Remove your ASM30 source code (.s) files from your project window.
2) Remove each of your ASM30  source code (.s) files from the MPLAB
 IDE editor window (right click ===> Close).
3) Change the extension of your ASM30  source code (.s) files from
lower case to uppercase: (.S).
4) Add your your ASM30 source code (.s) files back to your project.
5) Change your 'Active Toolsuite' to: Microchip C30 Toolsuite (instead of
Microchip ASM30 Toolsuite)
   (you can use the free Student Edition of C30)
6) Invoke 'Make' or 'Build All' to assemble your source code -- the text
substitution now works.
7) Now something like this is possible and assembles error-free just like
 in MPASM:

#define USART_TX_PIN            PORTC, #6
#define USART_TX_LATCH          LATC, #6
#define USART_TX_DIRECTION      TRISC, #6

     .       .       .
     .       .       .
     .       .       .

     BSET     USART_TX_LATCH

     .       .       .
     .       .       .
     .       .       .
