Your configuration is somehow messed up so that it's not recognizing you're building on OS/2. The command for gcc should look something like this:
gcc -o pathsub.obj -c -DOSTYPE=\"OS22\" -DOSARCH=\"OS2\" -DOJI -I../dist/include -I../dist/include `../nsprpub/config/nspr-config --prefix=../dist --cflags` -Wall -W -Wno-unused -Wpointer-arith -Wcast-align -Wno-long-long -Zmtd -Zomf -DNDEBUG -DTRIMMED -O3 -include ../config-defs.h -DMOZILLA_CLIENT ../../config/pathsub.c Open mozilla.src/mozilla/obj-i386-pc-os2-emx/config/autoconf.mk. Right near the end, MOZ_OS2_TOOLS should be set to EMX and MOZ_OS2_EMX_OBJECTFORMAT to OMF. Also, check mozilla.src/mozilla/obj-i386-pc-os2-emx/config-defs.h and add any of the following that may be missing: #define OS2 1 #define OS2EMX_PLAIN_CHAR 1 #define XP_OS2 1 #define XP_OS2_EMX 1 #define XP_OS2_FIX 1 #define XP_PC 1 h~
