The Unixware targets are still using the fixinc.svr4 shell script, not the
new C program. I tried just switching Unixware 7 over to using the
fixincl.sh script but found that the changes to introduce __STRICT_ANSI__
were required. inclhack.def has an #ifdef STRICT_ANSI that may suffice,
but I haven't pursued it (& need to check the uw7 usage matches the
patterns).
Your advice would be welcome Bruce, should we try to hack in the
avoid_wchar_t_type change into fixincl.svr4 or have a varient
routine that builds the C program with -DSTRICT_ANSI to get the SVR4
__STRICT_ANSI__ edifice in? Do we need autogen to do so?
