else # LINUX

#
#  For Linux builds, a completely different strategy is used.  ROOT & TOOLROOT
#  aren't used.  The GNU convention is to build using root-installed packages
#  (headers, libraries and tools) and anything unique to the build is self-
#  contained within the build tree.
#
#  Unfortunately, because of it's background, osprey needs a mixture of
#  different header files to build correctly on Linux.  These include:
#    1.  Component-specific headers in component source directories
#    2.  Header files dynamically generated as part of the build process
#    3.  The compiler-specific headers located in v7.4i/include
#    4.  A small set of Irix-supplied headers
#    5.  The Linux system headers
#    6.  The GNU headers
#    7.  "Extended" versions of headers from #3 & #4
#    8.  A patched version of STL (the current Mips version is too compiler
#        specific and the current Linux version is too out-of-date)
#  In some cases headers from #3 & #4 override headers from #5 & #6.  In some
#  cases headers from #5 & #6 override headers from #3.  In all cases, headers
#  from #7 & #8 override headers from #5 & #6.
#
#  There isn't an include search path that will work correctly referencing the
#  headers in place.  We need to build the compiler in both Mips and Linux
#  environments.  The headers in #1 can't be radically changed (they are
#  shipped to Mips customers) or eliminated.  We also want to "be a good
#  citizen" on Linux hosts and not edit/replace "system" headers in #3 & #4.
#  Finally, we don't want a particular header file to exist in more than one
#  location in our source tree.
#
#  So the scheme is to "install" a subset of the headers from #3 and all the
#  headers in #4, #7 & #8 in a local target build directory (ie:
#  targi32/include).  Then the include search path becomes:  #1 (in place in
#  workarea's source tree), #2 (in appropriate build directory), "installed"
#  headers, #6, #5.  Since #6 and #5 are automatically supplied by the GNU
#  compiler driver, we don't need to specify them.  This is very similar to
#  the include search path for Mips-hosted builds except that item #2 and the
#  "installed" headers are located in ROOT and we don't have to hand craft
#  the "installed" headers to avoid conflicts.
