Can't build gcc trunk on cygwin: cp/parser.c:6484: error: `pending_lang_change' undeclared (first use in this function)

[Christian Jönsson]

This was on a Windows XP SP1/cygwin P4 system with these packages:

binutils  2.13.90 20021118  (cygwin ver. 20021117-1)
cygwin    1.3.18-1
dejagnu   1.4.2.x           (cygwin ver. 20021217-1)
gcc       3.2-3

In tree joined gcc and binutils cvs trunks.

This patchlet from DJE helps on linuxppc and darwin. Though I don't know 
if correct.

Actually it's in c-lex.c.  Ugh.

For me on linuxppc the bootstrap went through.
Should do a make -k check. But I wait until next year since I fu** my 
firewire drive.

P.s, happy new year.... !

This appears to correct the bootstrap breakage on x86 and PPC.  I
suspect Mark's recent patch would do what you want,
