On most systems where many fixes +are required, this is accomplished by putting most of the functionality +into a binary executable. On systems that had dedicated fixinc.* shell +scripts, those scripts are still used by default until they can be +converted. + +KNOWN PROBLEMS + +There may be some systems on which the fixinc binary program appears +to be functional, but fails to work. Current thinking is that this +is due to some new process limitations (fork() calls) on those +systems. If you are experiencing this problem, then copy the script +${src}/gcc/fixinc/inclhack.sh into ${builddir}/gcc/fixinc.sh and run +make again. + +Oh, yes, please also report the problem with a description of +the failure mode (symptoms) and the output from: + + egcs/config.guess + +TO DO + +* fixincl needs to be converted to use gcc's system.h, libiberty, and + other portability frameworks. + +* FIXME: XXX needs to have tests for file descriptors > 10 or 12 added + to detect/solve XXX. + +* + + + +THEORY OF OPS + +inclhack.def contains a list of potential fixes to be applied to the +system headers.
