When parsing Flags.pri included  mutliple times form subdirectory projects 
program returns parse error, at the same time qmake (Qt 4.3.x) work properly with it.

 QMAKE_LFLAGS_RELEASE= -pg

}

Additionally 
Parsing following line 
"=================" 
in .pro files causes as well parse error. 

BTW. 
It would be nice to have line number and token name included to parser string error. 





Additionally 
When parsing project files ... having line od '=' chars return parse error. When qmake parser does'nt do that. 

I would be glad to include simplified project for which those errors occur. But this is my first bug report and I don't know how to include this file here. 

P.S.
Forgive me my English it is not my primary language.
