+<para> Normally, LWASM makes a distinction between PC and PCR in program
+counter relative addressing. In particular, the use of PC means an absolute
+offset from PC while PCR causes the assembler to calculate the offset to the
+specified operand and use that as the offset from PC. By setting this
+pragma, you can have PC treated the same as PCR. </para>
