[Flang] Preprocessor does not work correctly in if statement #115676
Description
Version of flang-new : 20.0.0(74b56c7eb807e2ba54bd7a2bcfda5d0bceff1c0c)/AArch64
Preprocessor does not work correctly in if statement.
When I look at the file (snggo785_2.i) processed by the preprocessor, lines 3, 5, and 20 are processed correctly, but line 19 is not.
For the following line
19 if((1.e.2)/=3) print *,'error-1'
Expect to translate as follows
19 if((1.eeeee.2)/=3) print *,'error-1'
The following are the test program, Flang-new, Gfortran and ifx compilation result.
snggo785_2.F90:
#define e eeeee

module procedure ir,rr
end interface operator(.e.)

intent(in)::k1,k2
ir=k1+k2

if((1.e.2)/=3) print *,'error-1'

print *,'pass'
