In our sources we use a macro UNALIGNED to mask
compiler specific attributes in declarations, e.g. with
g++:

#define UNALIGNED __attribute__((__packed__))

If we use this in structures like the following the
code is broken by GC:

struct Bit_mask {
unsigned short flag1:1 UNALIGNED;
unsigned short flags2:2 UNALIGNED;
unsigned short flags3:3 UNALIGNED;
};

will be modified to

struct Bit_mask {
unsigned short flag1 : 1U NALIGNED;
unsigned short flags2 : 2U NALIGNED;
unsigned short flags3 : 3U NALIGNED;
};

The lexical analysis in lexi.c seems way to optimistic
in which blanks could be skipped.

The quick fix we used to solve this is attached. We
are using version 1.140.
