Re: Cross compiling NSPR for an xtensa processor

Hello Wan-Teh,
                    From the nspr porting instructions I saw that the
jmp_buf information from _linux.h is used only for the local NSPR
version. And as i have the pthread library the USE_PTHREADS=1 in the
autoconf.mk. So will I be correct in thinking that the jmp_buf
information will not be used.

Thank you
Pradeep
