Subject: [Boost-build] mingw 32 and 64 bit targets
From: Roland Schwarz (roland.schwarz_at_[hidden])

Until boost version 1.57 I have been able to put a 64 bit and a 32 bit
mingw compiler specification into a *-config.jam file. I used to
differentiate between the both by specifying different <flavor> 's.

Now with boost 1.59 I see some configuration checks which give me:

Performing configuration checks

    - 32-bit : no
    - 64-bit : yes
    - arm : no
    - mips1 : no
    - power : no
    - sparc : no
    - x86 : yes

The availability of 32-bit changes if I put the 32 bit compiler first
into the config file.

So my question is: How do I specify that a specific compiler supports 32
or 64 bits? Or how do I make the configuration checks pick up both

Or will I need a separate config file per compiler ?

Thank you,
