Overriding compiler switch in MEX

Hello,
I am using MATLAB 2019a and trying to create a MEX file from Fortran code.
My Fortran compiler is 'Intel Parallel Studio XE 2019 for Fortran with Microsoft Visual Studio 2017'.
The MEX configuration has a default compiler switch /integer-size:64. However, I have some legacy Fortran code, where integers are not explicitly declared, and I don't want these to be taken as 64-bit integers. So, I try to override this by
mex -v COMPFLAGS='$COMPFLAGS /integer-size:32' -largeArrayDims filename
But this results in the command line
ifort /c /nologo /fpp /Qprec /MD /fp:source /assume:bscc -I"C:\Program Files\MATLAB\R2019a\extern\include" /DMX_COMPAT_64 /DMATLAB_DEFAULT_RELEASE=R2017b /DUSE_MEX_CMD /DMATLAB_MEX_FILE /integer-size:32 /integer-size:64 /O2 /DNDEBUG filename
where somehow the compiler switch /integer-size:64 gets stuck in after my switch, and I get the warning,
ifort: command line warning #10121: overriding '/integer-size:32' with '/integer-size:64'
I am not finding the /integer-size switch in my mex_FORTRAN_win64.xml file, and I don't know what is causing it to get appended.
Any advise on how I could stop that switch from getting appended to the commandline, or how I could override it?
Thank you.
Siva

Hope is about all there is for TMW ever doing anything really useful with the mex interface it seems...
I railed at them extensively 20+ years ago and all fell on totally deaf and apparently completely disinterested ears...
