[CMake] Question about strange Android behavior

[Christopher Broadbent]

We hit this on android too, and moved across to using 
std::numeric_limits in our code. The root cause for us was
differences between the C standard libraries on android, and the one we 
were running on Linux.

https://stackoverflow.com/questions/986426/what-do-stdc-limit-macros-and-stdc-constant-macros-mean 
might give
you a fix. To investigate, I'd want to run both builds with "make 
VERBOSE=1" and compare the commands that cmake
is generating for the failing files, just in case there is something 
more severe happening behind the scenes.
