teach the Autotools build system that PHP headers are not part of Graphviz

tl;dr: this removes 166 spurious compiler warnings.

When building the Graphviz PHP bindings, PHP headers are included and the build
system was treating these as local includes; things to be warned about. With PHP
7, this was generating a *lot* of warnings. Many of these issues are already
fixed upstream in PHP but, moreover, these files are not part of Graphviz and
warnings about them should not be part of the Graphviz build.

This commit teaches the compiler that the PHP headers are system headers, not
local headers, and warnings about them should be suppressed.

Some open questions:

  1. I explored finding an alternative `--includes` option to `php-config` that
     would give `-isystem` prefixed paths instead of `-I` prefixed paths. It
     would be cleaner than this commit to do such a thing in configure.ac, but
     such an option does not appear to exist.

  2. Vim highlights the use of `$(patsubst …)` as if it is an error. Is it
     illegal to use GNU Make functions in Makefile.am files? I do not think so,
     but given how long both Autotools and Vim have co-existed for, I am
     wondering if this highlighting is deliberate and telling me something I am
     missing.

3 years agoCI: remove obsolete exporting of SHELLOPTS = "igncr" in windows-cygwin-cmake-build

CI: remove obsolete exporting of SHELLOPTS = "igncr" in windows-cygwin-cmake-build

This is no longer necessary since crlf is now replaced with lf in all
text files in the repository before Cygwin starts.

Exporting SHELLOPTS has the negative side effect that other flags such
as -e, -u and -x are inherited by child processes which could cause
invoked bash scripts to fail (because of -u) and abort (because of -e)
unintentionally. While this does not happen in the current Cygwin
CMake build, this has been observed in Cygwin autotools builds that
will be introduced in an upcoming MR. This commit ensures that this
can not occur in the future for CMake builds either.

The -x option is more or less harmless, but causes excessive logging
in invoked scripts. This can be seen in
e.g. https://gitlab.com/graphviz/graphviz/-/jobs/1593005342.

smyrna update_columns: fix incorrect call to initGrid

Thanks to backwards compatibility with K&R C, a function declared with no
parameter list takes an unspecified number of parameters. So it is legal to call
such a function with any arguments. Nevertheless on macOS Clang notices:

  tvnodes.c:354:18: warning: too many arguments in call to 'initGrid'

as noted by Stephen.¹ This commit both fixes the call and alters `initGrid` to
have a more strict signature. This appears to be the correct fix to me as `str`
is duped into `g->flds` below this which is what I think the mistaken call to
`initGrid` believed was happening inside `initGrid`.

fix: do not overwrite exparse.h during MSBuild compilation

Commit 09973560cc67c5277df8732ebba75da784afbe51 altered exparse.h to be a static
checked-in file instead of generated by Bison. This passed CI testing, but
unfortunately it was not noticed that on Windows MSBuild this resulted in the
build process still generating exparse.h and overwriting the in-repo copy.

This change reverts the Bison command used during MSBuild to generate the
default y.tab.c/y.tab.h output, more closely aligning it with the other build
systems.
