--- This is an SGI Irix version of this package
-
--- This procedure creates the file "a-tcbinf.c"
--- "A-tcbinf.c" is subsequently compiled and made part of the RTL
--- to be referenced by the SGI Workshop debugger. The main procedure:
--- "Gen_Tcbinf" imports this child procedure and runs as part of the
--- RTL build process. Because of the complex process used to build
--- the GNAT RTL for all the different systems and the frequent changes
--- made to the internal data structures, its impractical to create
--- "a-tcbinf.c" using a standalone process.
