The internal hc preprocessor/hc compiler combination can not compile the
following simple file:
% cat test.c
#include <sys/signal.h>
% cc -Hnocpp -c test.c
E "/usr/include/sys/signal.h",L139/C1: (syntactic) unexpected symbol:'}'
REPAIR: '_far' was inserted before '}'@"/usr/include/sys/signal.h",L139/C1
Object module not generated.
%
It is not clear whether it is a preprocessor or compiler bug; it works fine
with /lib/cpp (the default).
This appears to be fixed with version 2 of the compiler, which we will
be shipping as /bin/hc2 in the 6.1 release.
Another point:
% cc -Hppo=test.out test.c
E : Undefined toggle:LONG_ENUMS
E : Undefined toggle:DOUBLE_MATH_ONLY
2 user errors No warnings
%
I should not be able to cause an internal error like this without any unusual
command line switches.

This is still broken in version 2, but in a different way:
[prometheus!raeburn:/tmp]
<1021 5:55am> % hc2 -Hppo=test.out test.c
/tmp/var003052: No such file or directory
Aborting(21)...
Exit 21 hc2 -Hppo=test.out test.c
[prometheus!raeburn:/tmp]
<1022 5:55am> % hc2 -Hppo test.c
[prometheus!raeburn:/tmp]
<1023 5:56am> %
According to the man page, the latter should have output some text, so
both are wrong. (The output file is produced, though.) I'll send
this to our IBM people....
