Mingw32 egcs 1.1.1, GCC_EXEC_PREFIX and CreateProcess

[Gilles Depeyrot]

Hi everyone,

I'm having a problem with Mingw32 egcs-1.1.1 concerning the
GCC_EXEC_PREFIX environment variable.

I launch and run egcs from inside an Win32 application using
a call to CreateProcess. This works fine except for the fact
that in this case, GCC_EXEC_PREFIX *must* be defined or I get
an error message:

gcc: installation problem, unable to exec `cpp'

The readme for Mingw32 egcs 1.1.1 states:

>Installation?

I have checked that GCC_EXEC_PREFIX is not defined at all in my 
environment.

I have checked that egcs compiles fine when run from the DOS command line.

Furthermore, if GCC_EXEC_PREFIX *is* defined, running gcc from an 
application
via CreateProcess works fine. If it is not defined, it does not work.

Keep up the great work
