d/dmd/expression.c includes math.h and port.h in that order.
math.h defines macros for:
isnan
isfinite
signbit
port.h then declares a struct with:
static int isnan(double);
static int isfinite(double);
static int isinfinity(double);
static int signbit(double);
The macros collide with the names in the struct declaration, causing a fatal compile time error.
A kludge (that seems to work) is to change expression.c to include port.h *before* math.h.
A clean long term solution is either:
a) make sure no file ever includes both math.h and port.h (this is probably impractical) or...
b) rename the offending names in port.h (and everywhere that refers to them)
I am not sure if this bug should be fixed in DGCC or upstream in the DMD compiler sources.
Thanks!
