+Subject: [PATCH 1/4] Resolved conflict between #define B and system headers
+
+regs51.h has pre-processor defines for special purpose registers (SPRs)
+of the s51 architecture which includes a "B" SPR.
+
+As a result, regs51.h contains the line:
+
+    #define B (0xf0)
+
+Unfortunately, the GCC headers contain function definitions such as this:
+
+    __m256bh _mm256_roundscale_pbh (__m256bh __A, int B);
+
+These GCC headers are imported via the winsock2.h.
+
+To prevent collision between the "B" define and usage of "B" in GCC's
+headers, this patch includes cmdutil.h early in the file, since
+cmdutil.h includes winsock2.h .
