Thomas,
I'm not getting any errors it is just that the output is so radically different
that the package
that processes the output files is having problems.
Attached is foo.h processed by both hurd and linux.
Thanks,
Barry

OK -- so a later compilation stage is choking on this and thus emitting
error messages?
Attached is foo.h processed by both hurd and linux.
Hurd:
enum __error_t_codes
{
EPERM = ((0x10 26) | ((1) 0x3fff)),
((0x10 26) | ((1) 0x3fff)) PRELUDE_ERROR_EPERM
Linux:
1 PRELUDE_ERROR_EPERM
So i'm guessing that either the later compilation stage is choking on the
presence of the Hurd version's enum definition, or on the Hurd's
pecularity of E* values and thus the PRELUDE_ERROR_* values not being
simple numerals. Whatever it is (and whatever that code is being used
for...) it needs to be extended to cope with this.

Strange output of gcc -E on GNU/Hurd
Hi folks, In looking at libprelude it generates a lot of files using gawk. The attached file is generated from gawk and then is run through gcc -E. On GNU/Hurd, I get significantly different results than I do from GNU/Linux. Anyone have a clue why that might be or where I would look to debug this? Thanks!

Barry deFreese, le Sun 15 Jul 2012 16:32:06 -0400, a écrit : On GNU/Hurd, I get significantly different results than I do from GNU/Linux. That's not very surprising for errno.h: GNU/Hurd has completely different errno values. And its defines are not to a mere integer, but to a macro call, which might disturb some nasty things that applications do with E* macros. Samuel
