Re: sys/cdefs.h required by gcc 2.95.3 but not 2.95.2. Why? Bug?

[Thomas Kaiser <home_cray at yahoo dot com>]

I found a reference to this problem posted in 1999
using gcc 2.95.2. Since _G_config.h is automatically
generated when compiling gcc (?), it looks for
sys/cdefs.h. If it can find it, it sets a flag.

My guess it that sys/cdefs.h is part of the SPARC box
that has been used to build gcc 2.95.3 on
sunfreeware.com. But it was not part of the
build-machine when 2.95.2 has been build roughly one
year ago.

I manually changed now _G_config.h to reflect this by
just replacing '1' into '0' at the appropriate
location. 

If someone from the gcc-team could confirm that this
is acceptable to do without breaking anything else I
would appreciate this. I do not like to edit files
that are labelled with "Do not edit this file".

Thanks,

GT
