f2c.exe.gz is a compressed Win32 console binary for f2c that runs under Microsoft Windows 9x and NT. It was compiled by Microsoft Visual C++ 6.0 by makefile.vc. Compression is by gzip, source for which is available by ftp in prep.ai.mit.edu:/pub/gnu. As a convenience, gzip binaries for several systems (with names of the form system.executable) and source for the gzip used to compress the *.gz files are available for ftp from netlib directory gnu/gzip. In particular, if you copy gnu/gzip/dos.executable to an MSDOS machine (in binary mode), rename it gzip.exe, and rename f2c.exe.gz f2c.exz and f2cx.exe f2cx.exz, then on the MSDOS machine you can recover f2c.exe and f2cx.exe by executing "gzip -dN f2c.exz f2cx.exz". "xsum f2c.exe f2c.exe.gz" should give you: f2c.exe b39b23e 245760 f2c.exe.gz efe20e82 133264 Last update: 6 May 2006
