This command provides a way to retrieve information about how Tcl was built. Without any options, the command returns the Tcl patchlevel, followed by the '+'-sign, followed by the fossil commit-id followed by a list of dot-separated tags. If a field is given, this command extracts that field as described below. Any other field value not mentioned below will always return "0". For official Tcl releases, the fields are:

::tcl::build-info clang: Returns the clang version number (as 4 digits) if Tcl is compiled with clang, 0 otherwise.
::tcl::build-info commit: Returns the fossil commit-id where Tcl was built from.
::tcl::build-info compiledebug: Returns 1 if Tcl is compiled with -DTCL_COMPILE_DEBUG, 0 otherwise.
::tcl::build-info compiler: Returns the compiler name (either clang, gcc, icc or msvc), followed by a dash and a (4-digit) version number.
::tcl::build-info compilestats: Returns 1 if Tcl is compiled with -DTCL_COMPILE_STATS, 0 otherwise.
::tcl::build-info cplusplus: Returns 1 if Tcl is compiled with a C++ compiler, 0 otherwise.
::tcl::build-info debug: Returns 1 if Tcl is not compiled with -DNDEBUG, 0 otherwise.
::tcl::build-info gcc: Returns the gcc version number (as 4 digits) if Tcl is compiled with gcc, 0 otherwise.
::tcl::build-info icc: Returns the icc version number (as 4 digits) if Tcl is compiled with icc, 0 otherwise.
::tcl::build-info ilp32: Returns 1 if Tcl is compiled such that integers, longs and pointers are all 32-bit, 0 otherwise.
::tcl::build-info memdebug: Returns 1 if Tcl is compiled with -DTCL_MEM_DEBUG, 0 otherwise.
::tcl::build-info msvc: Returns the msvc version number (as 4 digits) if Tcl is compiled with msvc, 0 otherwise.
