[luatex] compiling on MINIX3

Thanks, that indeed helps.
Any chance we can change build.sh?

---
 # try to find gnu make; we may need it
 MAKE=make;
 if make -v 2>&1| grep "GNU Make" >/dev/null
 then 
   echo "Your make is a GNU-make; I will use that"
 elif gmake -v >/dev/null 2>&1
 then
   MAKE=gmake;
+  export MAKE
   echo "You have a GNU-make installed as gmake; I will use that"
 else
   echo "I can't find a GNU-make; I'll try to use make and hope that works." 
   echo "If it doesn't, please install GNU-make."
 fi

That shouldn't break anything and makes it work on minix.

I've tried the _POSIX_SOURCE, but that didn't help, still the same:

gcc -DHAVE_CONFIG_H -I. -I../../../source/libs/zziplib -Iinclude -I../../../source/libs/zziplib/zziplib-0.13.60 -I/home/reviczky/minimals/luatex-beta-0.70.1/build/libs/zlib/include -D_USE_MMAP  -Wall -Wunused -Wimplicit -Wreturn-type -Wdeclaration-after-statement -Wno-unknown-pragmas -Wmissing-prototypes -Wmissing-declarations -g -O2 -MT stat.o -MD -MP -MF .deps/stat.Tpo -c -o stat.o `test -f 'zziplib-0.13.60/zzip/stat.c' || echo '../../../source/libs/zziplib/'`zziplib-0.13.60/zzip/stat.c

It looks like we can check for minix though by:

---
-#if defined(_AIX)
+#if defined(_AIX) || defined(__minix)
 #include <strings.h> /* for strcasecmp */
 #endif
---

Then it gets past zzip, but fails later on with:

Any clues on that one?

Thanks for your help.
