When compiling in 32-bit mode using the "r", "S" or "D" asm constraint with a char variable gcc will incorrectly emit %sil or %dil

/* uses %sil for e */
void func(int a, int b, int c, int d, char e)
{
	__asm__ volatile("%0 %1 %2 %3 %4" :: "r"(a), "r"(b), "r"(c), "r"(d), "r"(e));
}

void func(char c)
{
	__asm__ volatile("%0" :: "S"(c));
}

This occurs with gcc version 4.4.0 20081021 (experimental) svn revision 141272
and gcc version 4.3.2 (Debian 4.3.2-1)

Command line options used: -O2 -m32 -S
