Details:
- Fixed a compile-time error in bli_init.c when compiling with OSX's
clang. This error was introduced in 868b901, which introduced a
post-declaration struct assignment where the RHS was a struct
initialization expression (i.e. { ... }). This use of struct
initializer expressions apparently works with gcc despite it not
being strict C99. The fix included in this commit declares a temporary
variable for the purposes of being initialized to the desired value,
via the struct initializer, and then copies the temporary struct (via
'=' struct assignment) to the persistent struct. Thanks to Devin
Matthews for his help with this.
