I have done what's suggested in the FAQ.

My config.sys file:
FILES=15

autoexec.bat file:
@echo off
prompt $p$g
path c:\bat;c:\bin;c:\unixbin;c:\dos;c:\fprot;c:\djgpp\bin;
set temp=c:\temp

I am using Ms-dos 5.0

The mem program (dos 5) reports:

591568 largest executable program size

1048576 bytes total contiguous extended memory
1048576 bytes available contigous extended memory

go32 (version 1.12.maint3) reports:
Extended memory available 1020 Kb
Swap space available 131040 Kb

stubedit -v gcc.exe reports:
0x40000 (256k)	Minimum amount of stack space (bytes/K/M)
0 (0k)		Maximum amount of virtual memory to keep when spawning
0 (0k)		Amount of conventional memory to leave (bytes/K/M)

The environment variables are set up as before.

gcc hello.c or gcc -v hello.c

still gives
Unsupported INT 0x06
Invalid Opcode at eip= .... etc.

I have 2Mb of ram, amd386sx/sxl 20, ega card and monochrome monitor. The 
time taken to perform a compile is not important to me at this stage.

The readme file says that 4Mb of hard disk space and 512Kb of ram is 
required. 


Thanks
