Solaris2.7 bootstrap failure, cc cannot compile cpplex.c

[Kaveh R. Ghazi]

Hi Zack,

	When I compile cpplex.c on solaris2.7 using cc (WorkShop
Compilers 4.2), I get:

 > cc -c -DIN_GCC -DSVR4 -g -DHAVE_CONFIG_H
 > 	-I. -I../../egcs-CVS20000710/gcc
 > 	-I../../egcs-CVS20000710/gcc/config

If I use cc (WorkShop Compilers 5.0) I get:

 > "../../egcs-CVS20000710/gcc/cpplex.c", line 202: internal compiler
 > 		error: Wasted space
 > cc: acomp failed for ../../egcs-CVS20000710/gcc/cpplex.c


I believe the cause is the macro definition of T() in cpplex.c which
is "U STRINGX(e) + 4".  This appears to be done to remove the CPP_
prefix from the entries in TTYPE_TABLE.  I think if you instead create
the entries in TTYPE_TABLE without CPP_ and prepend CPP_ using CONCAT2
when desired it will probably fix the problem.

Or we could just take out the "+ 4" since its just for debugging
output printing (right?)

Does either approach sound okay with you?
