Re: errors on QNX 6.4.1

[mkraai]

The changes for the math.h errors don't
work, because @GNULIB_MATHL@ is defined to 1, so the whole condition evaluates
to true.

I forgot to mention that there's also
a problem determining the dependencies of getdate.y.  The command
fails with the following error:

getdate.y:116: error: negative width
in bit-field 'verify_error_if_negative_size__'

I believe this is because time_t is
unsigned on QNX.

Thanks! That means that the extended I/O modules fully work on QNX.

This command creates a test directory comprising all gnulib modules.
It's likely to find some bugs, and you already have two of them:

This is a bug in gnulib-tool and the maintainer-makefile module.
I'm committing this workaround:

2009-07-25  Bruno Haible  <address@hidden>

                
* gnulib-tool (func_create_testdir, func_create_megatestdir): Exclude
                
the maintainer-makefile module.

This is apparently due to some declarations in QNX's <math.h> header,
see <http://lists.boost.org/Archives/boost/2005/12/97593.php>:

  #define cosl(x) _LSin(x, 1)
  #define coshl(x) _LCosh(x, 1)
  #define logl(x) _LLog(x, 0)
  #define log10l(x) _LLog(x, 1)
  #define sinl(x) _LSin(x, 0)
  #define sinhl(x) _LSinh(x, 1)

I'm applying this fix:

2009-07-25  Bruno Haible  <address@hidden>

                
* lib/math.in.h (cosl, logl, sinl): Don't declare if they are already
                
defined as macros. Needed on QNX 6.4.1.

Thanks for these two reports. You can now retry the
"./gnulib-tool --create-testdir --dir=/tmp/testdir" command.
