a few minor problems building egcs-1.0.3a

[Tristan Savatier]

Here are a few minor problems that I got when
building egcs-1.0.3a on my Linux-x86 system.

1) In egcs-1.0.3a/gcc/configure.in, the following comment
confused my 'autoconf' (version 2.3):

# Configure the subdirectories
# AC_CONFIG_SUBDIRS($subdirs)

I get a message like "error: macro AC_CONFIG_SUBDIRS not defined"

It looks like old autoconf try to expend macros in comments!
I removed this line and it solved this problem.

2) After doing the configure, in the gcc directory of
the object tree, The Makefile contains:


# Compiler to use for compiling libgcc1.a.
# OLDCC should not be the GNU C compiler,
# since that would compile typical libgcc1.a functions such as mulsi3
# into infinite recursions.
OLDCC = cc

Unfortunately there was no link cc -> gcc on my system, so it failed!

I changed that to:

#OLDCC = cc
OLDCC = gcc

and go no further problems.  Maybe it should be said
somewhere that 'cc' should exist (and possible be a linked
to the old gcc) in order for 'make bootstrap' to work.

Note that I changed
TCFLAGS =
to
TCFLAGS = -mpentium -O6

to get a faster compiler!
