Where do I get asm/sigcontext.h?

When I tried to install a garbage collector from the source, make included /usr/include/bits/sigcontext.h which contains the line #include which is not found, and make terminates with an error message. Now what package do I have to install in order to get that asm/sigcontext.h file? I am using SuSE 7.1. The last lines of the make output follow below. ------------------------------------------------------------------------------ In file included from /usr/include/signal.h:309, from alloc.c:23: /usr/include/bits/sigcontext.h:27: asm/sigcontext.h: No such file or directory make: *** [alloc.lo] Error 1 ------------------------------------------------------------------------------ ------------------------------------------------- Frank Hrebabetzky Tel./Fax: +55 / 48 / 235 1106 Florianopolis email: frankh@terra.com.br Brazil
