[Bug fortran/40898] STDCALL mangling problem for strings @8 instead of @4

[burnus at gcc dot gnu dot org]

------- Comment #1 from burnus at gcc dot gnu dot org  2009-07-29 07:04 -------
Function declaration

       function LoadLibrary(lpFileName) bind(C,name='LoadLibraryA')
!gcc$ ATTRIBUTES STDCALL :: LoadLibrary
         use ISO_C_BINDING

... and use

hmodule = LoadLibrary('fun.dll'//achar(0))

... and dump

hmodule = loadlibrary (&"fun.dll"[1]{lb: 1 sz: 1});

Reported error:

  undefined reference to `LoadLibraryA@8'

For a 32bit system, one expects a single 4-bye pointer and thus @4. However, I
do not see any reason why it should be 64bit instead of 32bits. It also cannot
be a 64bit Windows as one there does not use STDCALL.
