Including <stdint> didn't help.

Some more googling turned up that "int64_t is not defined on MingW" (see
https://rt.cpan.org/Public/Bug/Display.html?id=82369, 1st answer). Don't
know how accurate / up-to-date this answer actually is.
But maybe the problems I hit are also related to the use of C rather than
C++

I've replaced the .mex files (in C) by .oct files (in C++) and those get
compiled and do work fine;  that said I didn't use int64_t there. 
So my problem is solved. 
Perhaps .oct files are more appropriate in OF packages than .mex files
anyway (?)
