env.CXXFile(target = 'bar', source = 'bar.yy')
.EE
+.IP M4
+Builds an output file from an M4 input file.
+This uses a default $M4FLAGS value of
+.BR -E ,
+which considers all warnings to be fatal
+and stops on the first warning
+when using the GNU version of m4.
+Example:
+
+.ES
+env.M4(target = 'foo.c', source = 'foo.c.m4')
+.EE
+
.IP Jar
Builds a Java archive (.jar) file
from a source tree of .class files.
.IP LINKCOM
The command line used to link object files into an executable.
+.IP M4
+The M4 macro preprocessor.
+
+.IP M4FLAGS
+General options passed to the M4 macro preprocessor.
+
+.IP M4COM
+The command line used to pass files through the macro preprocessor.
+
.IP MSVSPROJECTCOM
The action used to generate Microsoft Visual Studio
project and solution files.
- Fix handling of library prefixes when the subdirectory matches
the prefix.
+ From Timothee Bessett:
+
+ - Add an M4 Builder.
+
From Charles Crain:
- Use '.lnk' as the suffix on the temporary file for linking long
