bits/mathinline.h change from 2. June breaks i586

[Thorsten Kukuk]

Hi,

the following patch:

2003-06-02  Bernd Schmidt  <bernds@redhat.com>

        * sysdeps/i386/fpu/bits/mathinline.h (sqrt, __sqrtl, ldexp,
        ldexpf, ldexpl): Only define if __FAST_MATH__.

breaks compiling of glibc on i586. I get the following error:

/usr/src/packages/BUILD/glibc-2.3/cc/stdlib/drand48_r.o.dt
In file included from ../math/math.h:362,
                 from ../include/math.h:3,
                 from drand48_r.c:21:   
../sysdeps/i386/fpu/bits/mathinline.h: In function `ldexpf':  
../sysdeps/i386/fpu/bits/mathinline.h:590: error: `__ldexp_code' undeclared (first use in this function)
../sysdeps/i386/fpu/bits/mathinline.h:590: error: (Each undeclared identifier is reported only once
../sysdeps/i386/fpu/bits/mathinline.h:590: error: for each function it appears in.)
../sysdeps/i386/fpu/bits/mathinline.h:591: warning: no return statement in function returning non-void

I don't think the patch is correct or complete, since ldexpf is not
wrapped by __FAST_MATH__.

Since I couldn't find the reason for this change, I don't know if the
appended patch is correct. At least it fixed my problem and glibc
compiles again.

  Thorsten
