Package: chemeq
Version: 2.3
Severity: important
Tags: patch
chemeq fails to build on at least mips/mipsel because it mixes up C and
C++ namespaces. The appended patch removes the C includes, and uses the
C++ "long double" function templates for exp() and log().
[The reason why it failed on mips is that "long double" is there an
alias for "double", and the corresponding expl()/logl() functions
are only defined in the header when c99 standard is requested.
g++ however implies gnu++98 standard.]
