Intel 2025.0.1 takes an absurdly long time to compile pario/dra/disk.arrays.c

[jeffhammond]

This is not our problem but I'm putting it here for tracking.

At -O2, which is the default, Intel(R) oneAPI DPC++/C++ Compiler 2025.0.1 (2025.0.1.20241113) compile time appears to be infinite for pario/dra/disk.arrays.c. At -O1 and below, it's fine.
