I have been trying to install the GNU C/C++ compiler IA-64 on Red-Hat Linux so that we can run our utility programs against the Trillian compiler's header files. However, during the build process, I encounter the error:           In file included from /usr2/GnuPro/instdir/gcc/include/syslimits.h:7,                          from /usr2/GnuPro/instdir/gcc/include/limits.h:11,                          from ../../../../../src/newlib/libc/stdlib/std.h:4,                          from ../../../../../src/newlib/libc/stdlib/__adjust.c:7:         /usr2/GnuPro/instdir/gcc/include/limits.h:117: limits.h: No such file or directory             make[3]: *** [__adjust.o] Error 1         make[3]: Leaving directory `/usr2/GnuPro/instdir/i486-pc-linux-gnu/newlib/libc/stdlib'         make[2]: *** [all-recursive] Error 1         make[2]: Leaving directory `/usr2/GnuPro/instdir/i486-pc-linux-gnu/newlib/libc'         make[1]: *** [all-recursive] Error 1         make[1]: Leaving directory `/usr2/GnuPro/instdir/i486-pc-linux-gnu/newlib'         make: *** [all-target-newlib] Error 2   and the installation will not continue further. The build is apparently trying to recurse the various "limits.h" files in the include path, and is fauling to find one of the directories, or is looking in the wrong directory for the next "limits.h" in the include directory chain.   Has anyone else run into this? Is there an alternate way for me to obtain the GCC header files without going through an install?   Thanks in advance.   Lynn R. Feinauer
