[Ananth A]

Hi,

while emerging koffice, i got the following error

-----------------------


this seems to be an error in expm1 function, which is supposed to be
part of the mingw math library.  a brief search on google gave me this
link, which shows that it has been added to mingw.

http://www.cygwin.com/ml/cygwin-cvs/2005-q1/msg00108.html


however, in the math.h which i have in my mingw installation (3.4.5),
it just shows the expm1 function as TODO on line 457.

can anyone else confirm the same problem??
what can i do to fix the problems ?? any hints/suggestions ??


Thanks,
Ananth
