[7.99.20] Build error

	Hello,

	I'm trying to build 7.99.20 on one of my blade2000 and compilation 
aborts with following error:

dependall ===> tools/mdsetimage
dependall ===> tools/asn1_compile
lex.c:13:30: error: operator '>' has no left operand
  #define YY_FLEX_MAJOR_VERSION
                               ^

*** Failed target:  lex.lo

	Of course, I have deleted obj and tools directories. I obtain the same 
error. I have tried to delete src and to checkout a new src tree. Same 
error.

	Any idea ?

	Best regards,

	JKB
