This patch adds support for spaces in the install path on MinGW.
It does this by converting the Long version of the iverilog path
into a Short version that does not have spaces in it. If we don't
do this then we can not add support for other arguments with
spaces in the path or filename. It also modifies the driver-vpi
program to support spaces in the saved ivl path. This is done by
just enclosing the include and library path argument in double
quotes.
The issue on MinGW is that if you put the executable argument to
system in double quotes to escape embedded spaces then you can
not put the arguments in double quotes as well. If you convert
to a Short name then the spaces are removed and we can in the
future escape the arguments as needed.
In the MinGW version of iverilog-vpi (C version located in driver-vpi)
we must only look at the first word of the IVERILOG_VPI_CC definition.
A recent change to the configuration process made this equal to
"gcc -std=gnu99" which will not be found when looking for the
gcc executable. We nee to look for "<path>\\bin\\gcc.exe". This
patch modifies the driver to only use the first word when looking for
the compiler, but uses the full value when compiling.
Move the header files from includedir/verilog to .../iverilog
because the verilog name is a little too generic. The iverilog-vpi
command should handle the changes.
This configure option causes the installed commands to have
a suffix string that makes them distinct from other versions
that also have a suffix string. This allows for multiple
installed versions of Icarus Verilog.
Also, move installed C/C++ header files into a subdirectory of
their own under the target include directory, to make clearer
the purpose and source of those files.
