In the autorouter code, the value 0x80 is assigned to MATRIX_CELL, which is
an overflow for a signed 8-bit type. As this type is used as a bit mask,
there is no point in having a sign bit anyway.
The C++ preprocessor is actually not required to process "true" and "false"
correctly. This works in C if <stdbool.h> is included, because these are
then macros themselves, and resolved correctly, but C++ requires them to be
keywords, so no such macros exist, and the preprocessor can treat both as
undefined/zero.
Mostly cosmetic change, although there are compilers that choke on this.
The C++ standard specifies that classes contain themselves as members,
probably so they shadow any other definition of the same name for their own
member functions, but there is really no reason why the class name should
be duplicated here.
* Dick Hollenbeck also contributed commit r6440. I inadvertently forgot to set
the Bazaar author tag before I committed it. My apologies.
* Switch to static linking of libcurl and on linux and windows and also
statically link in only required portions of openssl.
* Add the required thread locks which openssl needs.
* Remove the get curl version call from BASEFRAME since it pulls in curl and
openssl into every derived wxFrame class link image.
* Remove curl function from PGM_BASE, switch to atexit() instead. Anything in
PGM_BASE made the singletops bigger.
* Tested on Linux, Windows, and OSX.
This class wraps the comparison function in a way that is compatible with
std::map and std::set. This, too is generally useful, so it should be moved
to the generic header.
At the same time, the criterium for less-than is changed from "equal to -1"
to "smaller than 0", because technically the comparison function may return
other values.
* Add sheet number that is set by schematic file load order. This duplicates
the previous SCH_SHEET_PATH behavior.
* Uncouple SCH_REFERENCE and SCH_REFERENCE_LIST from SCH_SHEET_PATH.
* Add - operator to SCH_SHEET for comparison purposes. This duplicates the
behavior of SCH_SHEET_PATH::Cmp().
