Hmm, I wonder why they need it:
[Use -fno-strict-aliasing for *all* C files in the runtime
Simon Marlow <[EMAIL PROTECTED]>**20060629082902
as a precautionary measure. It is definitely required for GC.c,
but it may well become necessary for other files in the future due to
our (mis-)use of the C "type system".
]
Are there any other packages or the "important portion" referred to
haskell?
Anyway, I am testing the attached fix, it was simple ordering problem
triggering hack checking analyzed flag someone added into tree-inline.
extern __inline double
strtod (void)
{
}
strtol (void)
{
return strtod ();
}
