Buffer is now 32K

Still crashes :(

Should the stack space also be increased ?


COMSPEC=C:\COMMAND.COM

VER=7
ARA=ON
TZ=+0400
PATH=H:\DJGPP\BIN;H:\DJGPP\BIN-OLD;C:\UXUTL;C:\;C:\OPENDOS
PROMPT=$d $b $t$_[OPENDOS 7.01] $P$G
TEMP=C:\TEMP
OPENDOSCFG=C:\OPENDOS
DJGPP=h:\djgpp\djgpp.env

(GO32.EXE v1 is in BIN-OLD)

stub.exe -v \djgpp\bin\make.exe
