isnan (and finite and log) from math.h are defined conditionally for WIN32 by k.h.
Solutions:
patch k.h to remove isnan — unreliable since k.h changes from time to time
fetch specific revision of k.h from code.kx.com and apply precise patch
#undef isnan after including k.h before including math.h (check whether k.h defines any reserved identifiers that could break math.h)
#undef WIN32 and _WIN32 before including k.h (perhaps redefine afterwards)
separate code so k.h and math.h aren't used in the same translation unit — overhead, especially in routines generated by wrap.h
