I downloaded the latest CVS version of djgpp and compiled it (using
tools downladed in binary form drom a DJGPP mirror). But there was a
problem: every time a program linked with the newly-compiled libc.a, a
link error occurred.

libc.a:undefined reference to '_environ' (in crt1.c and spawnp.c)

Example: symify.c in djgpp/src/debug/common

In order t make things work, I replaced one line in src\libc\crt0\crt1.c

extern char **_environ;

with

char **_environ;

Is that the right thing to do? Or is there a cleaner fix?

By the way, some more files in djgpp CVS tree still do not compile, even
with this modification: v2load.c in djgpp/src/debug/common, and
go32-v2.c in djgpp/src/stub give an error "undefined reference to
'environ'".
