           Summary: Gcc doesn't handle SGI's modularized compiler setup
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P1
         Component: bootstrap
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: rrr6399 at futuretek dot com
                CC: gcc-bugs at gcc dot gnu dot org

I'm attempting to get gcc 3.3.1 compiled on an SGI Origin with IRIX 6.5
and MIPSpro 7.4 compilers. On this system, they allow access to 
various versions of the compiler using the "module" command, such
as 
module load MIPSpro.7313b
or 
module load MIPSpro.74

Unfortunately this creates havoc for gcc who'd like to see the
files in /usr/include. For instance, the bootstrap compiler 
fails when it can't find math.h:

stage1/xgcc -Bstage1/ -B/u/ba/rrr6399/opt/gcc-3.3.1/mips-sgi-irix6.5/bin/   -g
-O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes
-Wtraditional -pedantic -Wno-long-long   -DHAVE_CONFIG_H  -o jvgenmain
java/jvgenmain.o java/mangle_name.o errors.o ./intl/libintl.a  
../libiberty/libiberty.a
ld32: WARNING 84 : ./intl/libintl.a is not used for resolving any symbol.
stage1/xgcc -Bstage1/ -B/u/ba/rrr6399/opt/gcc-3.3.1/mips-sgi-irix6.5/bin/ -c  
-g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes    -DHAVE_CONFIG_H    -I. -Ijava -I. -I./java -I./config
-I./../include java/gjavah.c -o java/gjavah.o
java/gjavah.c:29:18: math.h: No such file or directory
gmake[2]: *** [java/gjavah.o] Error 1

Apparently, the bootstrap gcc compiler is confused by the "module" setup on this
Origin.

The include files for MIPSPro7.4 are in /opt/MIPSPro/74/usr/include. I've tried 
specifying the location of the compiler include files using:

-I/opt/MIPSpro/74/usr/include 

such as:

stage1/xgcc -Bstage1/ -B/u/ba/rrr6399/opt/gcc-3.3.1/mips-sgi-irix6.5/bin/ -c  -g
-O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes
   -DHAVE_CONFIG_H  -I/opt/MIPSpro/74/usr/include  -I. -Ijava -I. -I./java
-I./config -I./../include java/gjavah.c -o java/gjavah.o

But end up with all of these errors:
