This means that 1.7 had introduced a bug not present in 1.6, and 1.7a fixes it.

IIRC it started in the OW C/C++ newsgroup with thread
OW 1.7 Bug (may be major):
#define TYPEFLAG(f, t) (((f)&(0xFFFF0001))==(t))
The disassembly shows it doing
and eax,0x00000001
instead of
and eax,0xFFFF0001
0FC7 8B 44 24 10 mov eax,dword ptr 0x10[esp]
0FCB 25 01 00 00 00 and eax,0x00000001
if (TYPEFLAG(flags, 0x00010001)) {
.. whatever..
}
IIRC it was introduced by Bart Oldeman doing an adjustment for the 16-bit code generator. ---
