because I know it's in there: I checked with `ar x _fixdfdi.o libgcc.a` and the symbol is in there, so I'm lost
and had to fix it this way. I tried all gcc and ld options I could find: no hope :( If someone can enlighten me:
feel free to let me know at sumthinwicked@users.sf.net! Much obliged.
PS1. I think for __fixunsdfdi they have made a circumvention by having to add STATICLIBRARY EGCC.LIB
PS2. http://gcc.gnu.org/ml/gcc-bugs/2004-01/msg01596.html might have found out the same problem there
