[Simh] SimH 3.6-0 (problems compiling VAX using MinGW) DIAGNOSIS

[Wilm Boerhout]

The cause seems to be this: in the makefile, symbols are defined for the 
VAX (and VAX780) folder names. These names are used then both for 
locating the modules to build, and for the "-I" switch, as in:

VAXD = VAX/
VAX = ${VAXD}vax_cpu.c ${VAXD}vax_cpu1.c ${VAXD}vax_fpa.c ${VAXD}vax_io.c \
    ${VAXD}vax_cis.c ${VAXD}vax_octa.c  ${VAXD}vax_cmode.c \
[snip]
    ${PDP11D}pdp11_vh.c ${PDP11D}pdp11_cr.c
VAX_OPT = -DVM_VAX -DUSE_INT64 -DUSE_ADDR64 -I ${VAXD} -I ${PDP11D} 
${NETWORK_OPT}

Output from "gcc -v" (below) shows that the "I ${VAXD}" results in gcc 
not including that folder in its include path. When I manually change 
"-I ${VAXD}" to "-I VAX", effectively omitting the forward slash, the 
build will go fine.

I cannot see how this has ever worked. Then again, this is my first 
experience with gcc, so what do I know?
