Building Erlang OTP nder QNX 6.3, I get the following error:

There is a problem with $ERL_TOP/erts/configure not passing the LDFLAGS
environment variable for test compiles, so ALL library tests fail. I
modified files $ERL_TOP/erts/aclocal.m4 and $ERL_TOP/configure.in in order
to locate pthread_create in the standard C runtime library. The
$ERL_TOP/configure.in produces a configure that works, wheras the
$ERL_TOP/erts/configure.in does not. At the top of file erts/configure.in:

AC_PREREQ(2.13)
AC_INIT(vsn.mk)

Commenting out AC_PREREQ(2.13), or changing it to AC_PREREQ(2.57) (the
actual autoconf version on the compiling machine) has no effect on the above
result. I have also installed autoconf 2.13 and gotten incompatibility
results with all the configuration files.

Any ideas anyone?

Cheers,
