Re: [Bug-gsl] Bug in gensymm.c

[Patrick Alken]

Hello,

  I am almost certain that the C standard allows you to assign 
a void* return value to any other pointer type.

  There are also good reasons for not casting the return value
of the alloc functions, see:

http://www.c-faq.com/malloc/mallocnocast.html

Is it possible that your compiler is operating in C++ mode? I believe
in C++ you need to cast the alloc call. But in straight C you do not.
