* [Bug bootstrap/19481] New: libgfortran doesn't build -- configure doesn't handle cabs() well

This one is strange. On i686-mingw, compiling gfortran fails with:
../../../gcc/libgfortran/generated/exp_c8.c:38: error: conflicting types for 'cabs'
/mingw/include/math.h:223: error: previous declaration of 'cabs' was here
make[2]: *** [exp_c8.lo] Error 1
make[2]: Leaving directory `/home/coudert/ibin/i686-pc-mingw32/libgfortran'
make[1]: *** [all] Error 2
I guess, somewhere in the configure process, the presence of cabs() in math.h
was not detected. This is not specific to i686-mingw, since the same thing
happens on mips-sgi-irix6.5 (which I reported as comment #7 in PR15266).
So, I submit a new PR (hope "component=bootstrap" was the right choice, not
sure) so that GNU build utils gurus can get this fixed. I am ready to give any
extra information needed, but I don't know what may be useful at that point.
PS: configure was a simple ../gcc/configure --prefix=/mingw --enable-languages=c,f95

I will note this definitation of cbas is not compatible with C99.

I worked around this bug, commenting a line in /mingw/include/math.h (I quote it
here for reference):
//_CRTIMP double __cdecl cabs (struct _complex);
The end of the compilation runs smoothly, but when I try to use gfortran, it
complains at link-time about missing symbol _ftruncate. Indeed, mingw doesn't
have a ftruncate (it has a chsize which has the same prototype and all), but the
libgfortran.a needs one (originally in unix.o). This can be worked around
(create an object file for ftruncate which call chsize directly and "ar -rv" it
into libgortran.a), but it should get fixed nonetheless.

The ftruncate problem should be fixed now.
Does this work fully or is cabs issue still there?

It looks like this issue with cabs declaration is fixed now, with an up-to-date
mingw. Closing the PR.
