Jakub's patch works for me on HPPA, and correctly exports the *l prototypes
with __NO_LONG_DOUBLE_MATH set.

Action items left:
1) Checkin a patch to libc-ports to define __signbitl as an alias of __signbit
on hppa.

2) Someone please add a stub to

The hppa port sets long-double-fcts = no in glibc
and this causes all the aliases to be created, otherwise you'd never
be able to link anything that used `l' ending math functions. Defining
__NO_LONG_DOUBLE_MATH is

- config/abi/pre/gnu.ver needs the __signbitl symbol mentioned as well.
- the patch has an empty #ifdef/#endif at the end
with this change the symbol is found in the library. checked with a native
build on hppa-linux.

I believe the problem is the symbol was exported when it shouldn't have
been.
How?

Yes, if gcc does not determine that sizeof (x) == sizeof (double) then it
would have to emit code for the if-then-else statement and this would create a
reference to an undefined __signbitl. Has this ever

The signbit macro is provided by math.h.
But it's not in the baseline files showing that it is exported. This question

There is no __signbitl export expected, from
config/abi/post/hppa-linux-gnu/baseline_symbols.txt. Where is this from?
Assume this would result in an abi_check FAIL?
FYI
gcc-4.4 hppa-linux results are fine:

Long double on hppa-linux is the same as double (64 bits).
