I can confirm the behavior on msys, but not that it works any
differently anywhere else:

msys:
$ uname -s -r
MINGW32_NT-6.0 1.0.13(0.47/3/2)
$ gawk --version
GNU Awk 3.1.7
$ echo "-1 2" | gawk '{printf "%f %f\n", $1, $2}'
-1.000000 2.000000

linux:
$ uname -s -r
Linux 2.6.31.6-desktop-1mnb
$ gawk --version
GNU Awk 3.1.7
$ echo "-1 2" | gawk '{printf "%f %f\n", $1, $2}'
-1.000000 2.000000

$ uname -s -r
CYGWIN_NT-6.0 1.7.1(0.218/5/3)
$ gawk --version
GNU Awk 3.1.7
$ echo "-1 2" | gawk '{printf "%f %f\n", $1, $2}'
-1.000000 2.000000

My hunch is that msys-1.0.11 had a bug, or there was a problem in an
older version of gawk.  I really wouldn't expect gawk's %f printf to act
any differently that C's:

#include <stdio.h>
int main(int argc, char *argv[])
{
	double d1 = -1;
	double d2 = 2;
	printf ("%f %f\n", d1, d2);
}


$ gcc -o bob bob.c
$ ./bob
-1.000000 2.000000
