[MITgcm-support] Error reading dx file with pathscale

[Martin Losch]

Hi David,
just to make sure: you need either set a CPP flag like this:
DEFINES='-D_BYTESWAPIO'
in the build options file or (which is probably faster) specify the  
appropiate compiler flag.
"-byteswapio" is the flag for the PGI compiler, I don't know what the  
Pathscale compiler does, but in the tools/build_options/ 
linux_amd64_pathf90 I found this:
FFLAGS='-convert big_endian'

Could that be the problem?
