contacts) take default values from the DRC section. Since both
are in lambda, but the DRC section uses a two-part integer and
modulus representation, if default values are taken before
scaling, the LEF layers may get rounded values. This has been
solved by marking values with -1 to indicate that they require
defaults, and then set those defaults (from scaled DRC rules)
after scaling all other tech values.
This commit makes the code (mostly) C99-compatible, enabling to compile
it without the -Wno-error=implicit-function-declaration flag. This
way, Magic becomes usable on arm64 architectures, specifically on Apple
computers with M1/M2 SoC.
tech file format "version" section. This can be used to specify the
version of magic that must be used to be compatible with the tech file.
This effectively supercedes the technology version number. (2) Changed
the behavior of "make" to set the version and revision numbers on doing
"make" instead of "configure". This allows the version to update
correctly after doing a "git pull" followed by "make" without doing
"configure" in between. (3) Fixed a couple of issues that were flagged
as compile-time warnings.
