fenv.h, fmin, fmax

Wednesday, 29 April 2009

Using inkscape-21256 snapshot (because release version has bug causing 
core dump when attempting to change fill color as reported numerous 
times).

src/display/nr-arena-shape.cpp  has
 #include <fenv.h>

But I don't see any use of floating-point definitions, 
FE* macros, or fe*() functions.

I commented that line out and inkscape built fine. (Also some platforms 
don't have any fenv.h.)

Also src/live_effects/lpe-dynastroke.cpp uses fmin and fmax. 

Some platforms don't have that. So I added to 
src/live_effects/lpe-dynastroke.cpp :

#define fmin(a,b) ((a)<(b)?(a):(b))
#define fmax(a,b) ((a)>(b)?(a):(b))

Also work/inkscape-21256/src/display/nr-filter.cpp refers to fmax but it 
is commented out.
