[OpenMP] icpx error

### Describe the bug

software environment: Intel oneAPI 2025.3

Running an OpenMP target offloading program https://github.com/ORNL/HeCBench/tree/master/src/mergeVS-omp will give the following error:
```
make
icpx -std=c++17 -Wall -I../mergeVS-cuda -O3 -fiopenmp -fopenmp-targets=spir64 -D__STRICT_ANSI__ -c main.cpp -o main.o
In file included from main.cpp:9:
./kernels.h:48:66: warning: multi-line // comment [-Wcomment]
48 | #pragma omp target teams distribute parallel for collapse(3) //\

PLEASE append the compiler options "-save-temps -v", rebuild the application to get the full command which is failing and submit a bug t to https://software.intel.com/en-us/support/priority-support which includes the failing command, input files for the command and the backtrace (if any).
