4.1.3 and mpfr

[Sisyphus]

Hi,

On win32 (MinGW compiler in the MSYS shell) I built GMP-4.1.2 with:
./configure --disable-static --enable-shared --enable-mpfr

Then cd to '.libs' and build a 'libgmp.lib' by running:
lib /out:libgmp.lib /def:libgmp-3.dll-def

Then cd to 'mpfr' and build a 'libmpfr.lib' by running:
lib /out:libmpfr.lib *.o

I then have all the files I need to build with VC 7 (as well as MinGW) - 
and everything works fine.

So ... I repeated the same procedure with GMP-4.1.3. Everything still 
works fine with MinGW, but with VC 7, when I build an mpfr app, I get 
the errors pertaining to '_alloca'. Here's a simple test script:

-------------------------------------------
#include <stdio.h>
#include <gmp.h>
#include <mpfr.h>

/* Additional header for Microsoft Visual Studio */
/* Stolen from MinGW/include/string.h */

#ifdef _MSC_VER
strcasecmp (const char * __sz1, const char * __sz2)
  {return _stricmp (__sz1, __sz2);}

strncasecmp (const char * __sz1, const char * __sz2, size_t 
__sizeMaxCompare)
  {return _strnicmp (__sz1, __sz2, __sizeMaxCompare);}
#endif

int main() {
    mpfr_t x;

    mpfr_init_set_ui(x, 75, GMP_RNDN);
    mpfr_log10(x, x, GMP_RNDN);
    mpfr_out_str(stdout, 10, 0, x, GMP_RNDN);

return 0;
}
----------------------------------------------

It builds and runs fine under 4.1.2, but under 4.1.3 compilation 
produces the following:

----------------------------------------------

I'm assuming that the 'mpfr' source has not changed between versions 
4.1.2 and 4.1.3, which by my reasoning makes this a gmp (not mpfr) 
issue. Apologies if either my assumption or reasoning is flawed :-)

Cheers,
Rob
