Hi all,

Stephen Kitt gave a solution in order to install bash as SHELL.
Thanks!, It works!

Moreover, I think I've found (another?) reason WHY DJGPP/bash
cant work form SHELL=

There is nothing wrong with bash itself. Just try with:
%DJDIR%\tests\libc\ansi\stdlib\shell.c

Compile it (say, with rhide) and it will fail again.
(thanks DJ for including this example! :-)

When you compile to .exe an STUB is prepended to it. This stub
assumes it runs on DOS v3.0+ and that's true (hope!), but it also
assume that after Environment Block (after Double Zero Mark) is
the running Path File.

Well, that is NOT TRUE when MSDOS dispatchs a login shell.
In fact, login shell MUST alloc its own Environment.

The asm program, I enclose, allocs a Env suitable for a DJGPP
compiled shell.

Comments to the this asm prog.:
     1) SHELL=X:\mkenv&ld.exe  a:\bash.exe -login
                             ^^
	MUST be exactly two spaces here (I dont know why :-(
     2) SHELL= pass ALL line into upper-case, mkenv&ld.asm turns
	it into lower-case again.
     3) I realize mkenv&ld.asm is not one of my better asm prog
	but it works :-)

Once bash is successful running:
	I've tested several things, one of them, is running
W3.1, and it WORKED!!, but when it exits crashs with:

bash$ Double Faul at eip=46199; flags=3246
eax=00000300  ebx=00000016  ecx=00000000  edx=000437c4
esi=000a7557  edi=000a47a4
ebp=000a7248  esp=00a723c  cs=a7  ds=af  es=b7  fs=8f  gs=bf
ss=af  error=0006

but my HD's led blinks from time to time ...

Finaly, Thanks a lot for porting bash to DJGPP

PS: Please, excuse my 'bad' English
