Hi JD ,
I'm not sure why it is not picking it up from MinGW
Can you try adding the the location of the math.h to the src/Makefile - see below - for me it is c:/MinGW/include. This worked ok for me but I'm still looking into why it is not picking it up automatically.
I didn't try that, but I will. What worked for me was these mods to my proj.conf: seems it defaults to the "minimal" C standard Lib.
